Answer:Option A.
Explanation:
Expression given in the question is (f g)(5).
We know when two functions are f(x) and g(x) then (f g)(x) represents the multiplication of two functions.
(f g)(x) = f(x).[g(x)]
For x = 5
(f g)(5) = f(5).g(x)
It may be represented by the operation as
(f g)(5) = f(5) × g(x)
Therefore, option A will be the answer.
