问题如下：
A futures contract is best described as a contract that is:
选项：
A.standardized.
B.subject to credit risk.
C.marked to market throughout the trading day.
解释：
A is correct. A futures contract is a standardized derivative contract. B is incorrect because through its clearinghouse the futures exchange provides a credit guarantee that it will make up a loss in the event a losing party cannot pay. C is incorrect because a futures contract is marked to market at the end of each day, a process in which the futures clearinghouse determines an average of the final futures trade of the day and designates that price as the settlement price.
中文解析：
A对，期货合同是标准化的衍生品合同。
B是不正确的，因为期货交易所通过其清算所提供信用担保，在损失一方不能支付的情况下，它将弥补损失，不面临信用风险。
C选项错误，C的意思是期货合约会在交易日内时时刻刻盯市，这是错误的。
期货合约的规则是“逐日盯市”，也就是每天收盘后结算当天的损益，而不是在一天之内时时刻刻都要结算。
怎么看出c说的是这一天之内时时刻刻都在结算？
