答案
参考答案：B
解析：If the margin balance falls below a specified level ( the maintenance margin) , additional capital (the variation margin) must be deposited in the account. Initial margin is the capital that must be in the trader's account before the initiation of the margin trade. Marking to market is when any loss for the day is deducted from the trader's account, and any gains are added to the account.
