transform和transfer

问题如下：

Derivatives are similar to insurance in that both:

选项：

A.

have an indefinite life span.

B.

allow for the transfer of risk from one party to another.

C.

allow for the transformation of the underlying risk itself.

解释：

B is correct. Insurance is a financial contract that provides protection against loss. The party bearing the risk purchases an insurance policy, which transfers the risk to the other party, the insurer, for a specified period of time. The risk itself does not change, but the party bearing it does. Derivatives allow for this same type of risk transfer. A is incorrect because derivatives, like insurance, have a definite, as opposed to indefinite, life span and expire on a specified date. C is incorrect because both derivatives and insurance allow for the transfer of risk from one party (the purchaser of the insurance policy or of a derivative) to another party (the insurer or a derivative seller), for a specified period of time. The risk itself does not change, but the party bearing it does.

中文解析：

B是正确的。保险是一种金融契约，为损失提供保护。承担风险的一方购买保险单，将风险在一定时期内转移给另一方，即保险人。风险本身没有改变，但承担风险的一方改变了。衍生品允许同样类型的风险转移。

A是不正确的，因为和保险一样，衍生品有一个明确的，而不是无限期的，生命周期和在一个特定的日期到期。

C是不正确的，因为衍生品和保险都允许风险从一方(保单或衍生品的购买者)转移到另一方(保险人或衍生品卖方)，在指定的时间内。风险本身没有改变，但承担风险的一方改变了。
