Answer:
The correct answer is C. Large hedge funds must register with the SEC.
Step-by-step explanation:
Due to their investment volume, they need to be registered in the database established by the SEC. This guarantees a tracking of each one of the hedging operations that are carried out, since they have a great impact on the markets in the event of a sharp drop. The other funds were not affected in the same way, because they do not need to report or file their information with the SEC.
