Answer: D

Reason: The prototype is a kind of global property that is available with nearly all objects. In order to know about an object, whether the object is a prototype (or a part of a prototype chain) of another object, the user can use the "isPrototypeOf()" method. For example, if the user wants to find out about z whether it is a prototype of "s" or not, user can write z.isPrototypeOf(s).
