I think the answer would be D. The demand for cattle increased in the North, which made the price increase.
Renaissance art (1350 - 1620 AD) is the painting, sculpture, and decorative arts of the period of European history known as the Renaissance, which emerged as a distinct style in Italy in about AD 1400, in parallel with developments which occurred in philosophy, literature, music, science, and technology. Renaissance art took as its foundation the art of Classical antiquity, perceived as the noblest of ancient traditions, but transformed that tradition by absorbing recent developments in the art of Northern Europe and by applying contemporary scientific knowledge. Along with Renaissance humanist philosophy, it spread throughout Europe, affecting both artists and their patrons with the development of new techniques and new artistic sensibilities. For art historians, Renaissance art marks the transition of Europe from the medieval period to the Early Modern age.
The body of art, painting, sculpture, architecture, music, and literature identified as "Renaissance art" was primarily produced during the 14th, 15th, and 16th centuries in Europe under the combined influences of an increased awareness of nature, a revival of classical learning, and a more individualistic view of man. Scholars no longer believe that the Renaissance marked an abrupt break with medieval values, as is suggested by the French word renaissance, literally meaning "rebirth". Rather, historical sources suggest that interest in nature, humanistic learning, and individualism were already present in the late medieval period and became dominant in 15th- and 16th-century Italy, concurrently with social and economic changes such as the secularization of daily life, the rise of a rational money-credit economy, and greatly increased social mobility. In many parts of Europe, Early Renaissance art was created in parallel with Late Medieval art.
Origins
Many influences on the development of Renaissance men and women in the early 15th century have been credited with the emergence of Renaissance art; they are the same as those that affected philosophy, literature, architecture, theology, science, government and other aspects of society. The following list presents a summary of changes to social and cultural conditions which have been identified as factors which contributed to the development of Renaissance art. Each is dealt with more fully in the main articles cited above. The scholars of Renaissance period focused on present life and ways to make human life evolve and improve in its entirety. They did not pay much attention to medieval philosophy or religion. During this period, scholars and humanists like Erasmus, Dante and Petrarch criticized superstitious beliefs and also questioned them. The concept of education also widened its spectrum and focused more on creating 'an ideal man' who would have a fair understanding of arts, music, poetry and literature and would have the ability to appreciate these aspects of life. During this period, there emerged a scientific outlook which helped people question the needless rituals of the church.
Classical texts, lost to European scholars for centuries, became available. These included documents of philosophy, prose, poetry, drama, science, a thesis on the arts, and early Christian theology.
Europe gained access to advanced mathematics, which had its provenance in the works of Islamic scholars.
The advent of movable type printing in the 15th century meant that ideas could be disseminated easily, and an increasing number of books were written for a broader public.
The establishment of the Medici Bank and the subsequent trade it generated brought unprecedented wealth to a single Italian city, Florence.
Cosimo de' Medici set a new standard for patronage of the arts, not associated with the church or monarchy.
Humanist philosophy meant that man's relationship with humanity, the universe and God was no longer the exclusive province of the church.
A revived interest in the Classics brought about the first archaeological study of Roman remains by the architect Brunelleschi and sculptor Donatello. The revival of a style of architecture based on classical precedents inspired a corresponding classicism in painting and sculpture, which manifested itself as early as the 1420s in the paintings of Masaccio and Uccello.
