Accountability is answerability, blameworthiness, liability, and the expectation of account-giving.[1] As an aspect of governance, it has been central to discussions related to problems in the public sector, nonprofit and private (corporate) and individual contexts. In leadership roles,[2] accountability is the acknowledgment and assumption of responsibility for actions, products, decisions, and policies including the administration, governance, and implementation within the scope of the role or employment position and encompassing the obligation to report, explain and be answerable for resulting consequences.

The similarity between the two Industrial Revolutions is that they both involved an increase in the degree to which machines were being used to do tasks that had once been done in other ways. Yes, there were differences in that the earlier Industrial Revolution was more about things capital goods like steam engines while the second was about consumer goods. But, in both cases, the main thing that was going on was an increase in the use of machinery. This is what they have in common and what makes it legitimate to call both of these "Industrial Revolutions."
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.
