听力原文： Currency options may have two kinds of value, intrinsic value and time value. If and to the extent that an option would currently be profitable to exercise, it is said to have intrinsic value. In the case of a call, if the spot price is higher than the option exercise price, the option has intrinsic value. In the case of a put, if the spot price is less than the option exercise price, the option has intrinsic value. Such options are said to bein-the-money'. If the opposite is true of either calls or puts, they have no intrinsic value and said to be out-of-the-money'.28. What are the two kinds of value do currency options have?29.When does a call option have intrinsic value?30.What is the option said to be if it has intrinsic value?(28)A．Intrinsic value and time value.B．Internal value and external value.C．Exchange value and time value.D．Real value and stated value.

You want to use te Coherence Java APIs to directly cached POJOs. Consider this snippet of code： NamedCache cache - CacheFactory.getCache（"mycache"）； cache.put（new Integer（I）f "hello"）； cache.put（T，"hi"）； cache.put（new Long（II），"hey"）； This code inserts three objects into the cache. Why ？（）A、 hashCode（） and equals（） method for each object type is different so a different key is usedB、 each object value string is different so a different value is inserted on each putC、 equals（） and compare（） method is different for each putD、 POF need to be implemented for this to work properly
