To briefly compare both terms, geography refers to the study of the physical features of the earth as well as its inhabitants or the population; whereas, geology refers to the study of the structure of the earth, its development as well as its origin.
It all depends on the definition of the term Modern Era. The word modern comes from Latin word modo, which means right now or just now. It was used for the first time during the Renaissance in Italy to bring attention to the great rediscoveries of sciences, the arts, history and politics of Classical antiquity and the subsequent discoveries and progresses accomplished like the Age of Discovery.
If such definition is used as the basis for this question then the answer is definitely C.The establishment of global empires.
Indeed, since during the previous periods, Empires were limited to their immediate geographic areas. There had been some attempts to explore areas that were located much farther like the Vikings and their travels to Greenland and North America.
However, it was the Europeans: and to some lesser extent the Chinese, that actually discovered (in the literal sense of removing the cover) the Americas for the entirety of the world. The discovery paved the way for the emergence of Global Empires that were completely unprecedented in the history of humanity since they spanned several continents. For instance, the Global Spanish Empire Under Philip II of Spain in the 16th Century that spanned the continents of Europe, the Americas, Africa and Asia.

When the profit matter comes to the business, the monopolistic firms earn profits slightly above their costs in the long run. Because barriers to entry are low, other firms have an incentive to enter the market, increasing the competition. As a result to survive in the market the profit margin gets lower. Therefore, they just make the profit above their costs.
