单选题 Which of the following statements is FALSE?

A、 Hedgers trade to reduce some preexisting risk exposure.
B、 The clearinghouse guarantees that traders in the futures marker will honor their obligations.
C、 If an account rises to or exceeds the maintenance margin, then the trader must deposit variation margin.

【正确答案】 C

【答案解析】If an account rises to or exceeds the maintenance margin, no payment needs to be made, and the trader has the option to remove the excess funds from the account. Only if an account falls below the maintenance margin does variation margin need to be paid to bring the level of the account back up to the level of the initial margin.
