Which sector overtook TTH as the largest revenue sector?

• A. TTH
• B. HML
• C. FS overtook TTH as the largest revenue sector
• D. A&UI

Answer: (C)

Understanding how rankings change in revenue sectors helps here: when one sector overtakes another, it becomes the new leader in total revenue. The statement that names the overtaking sector and the one it surpassed directly answers who is now on top. In this case, the sentence FS overtook TTH as the largest revenue sector explicitly says that FS has become larger than TTH, which is exactly what the question asks for. The other statements either keep TTH as the leader or attribute the overtaking to a different sector, which wouldn’t answer who actually overtook. So the sentence that specifies FS overtook TTH is the best choice because it clearly identifies the new leader and the change in ranking.
