i think it is B

Step-by-step explanation:

B) fog(x) = 2x(x^2-1)

Step-by-step explanation: F x G is the combination of f(x) and g(x)

2x x x^2 is basically 2x^3, but must be factored.

2x and x^2 cannot be simplified any more, so the 2x is moved to the left whilst the x^2 is moved to the right.

So, your answer is B.
