Read the two statements and choose the correct option.

I. Integrating the marginal cost gives the total cost up to a constant, and that constant is the fixed cost.

II. The fixed cost can be found from the marginal cost function alone.

Explanation

1. 01

   I: $C(x) = \int MC\,dx + k$, and $C(0) = k$ is the fixed cost. True.

2. 02

   II: differentiating removes the fixed cost, so MC alone cannot bring it back; one more fact, such as $C(0)$ or the cost of some output, is needed. False.
