Answer #1

1. If the marginal value of some variables is above the average value of the variable, then the average value must be rising. Hence, option(C) is correct.

2. The fixed costs of a firm are costs that stay the same regardless of the amount of output produced. Hence, option(A) is correct.

3. In the short run, TVC   increases with increasing output.Hence, option(B) is correct.
