Answer:  The correct option is

(A)  If F and G differ by a constant, then f = g.

Step-by-step explanation:  According to the given condition, we have

[tex]F'(x)=f(x)~~~\textup{and}~~~G'(x)=g(x).[/tex]

We are to select the correct statement.

Let F(x) = p(x)  and  G(x) = p(x) + c, c - constant.

Then, we get

[tex]F'(x)=p'(x)~~~\textup{and}~~~G'(x)=p'(x).[/tex]

Therefore,

[tex]F'(x)=G'(x)\\\\\Rightarrow f(x)=g(x)\\\\\Rightarrow f=g.[/tex]

Thus, if F and G differ by a constant, then f = g.

Option (A) is CORRECT.
