Answer: A
Step-by-step explanation:
If you multiply f(x) and g(x) together, you will also have to multiply 1/x and 2x. So:
(f * g)(x) = 1/x * 2x
(f * g)(x) = 2x/x
(f * g)(x) = 2
This tells you that the value of x does not matter because the equation will always equal 2. Therefore, A is the only possible solution.
