Answer:

  A) the elements in the domain of f(x) for which g(f(x)) is defined

Step-by-step explanation:

(g circle f)(x) means g(f(x)). In order for a value (x) to be in the domain of this function, f(x) must be defined. That is, x must be in the domain of f(x). In addition, g(f(x)) must be defined.

These requirements are expressed in choice A.
