Answer:
Option A.
Step-by-step explanation:
The given expression is
[tex](fg)(5)[/tex]
According to the composition of functions, if f(x) and g(x) are two functions, then
[tex](fg)(x)=f(x)\cdot g(x)[/tex]
Substitute x=5 in the above formula, to find the expression which is equivalent to the given expression.
[tex](fg)(5)=f(5)\cdot g(5)[/tex]
Therefore, the correct option is A.
