Answer:
Option A, Conquest, is the right answer.
Explanation:
The term culture diffusion is used to refer to the spread of a particular cultural belief and social activities of a group of people to another. Culture diffusion can take place through many different ways such as conquest, technology, religion, migration etc. As a result, the people of different areas, ethnicities, nationalities and religions share common culture sometimes.
The culture diffusion that spread due to the victory of one country in war is called cultural diffusion through conquest. It is so because prior to the war the people of the defeated country had their own culture to follow but after their conquest, the culture of the winner country spread throughout the defeated nation.
