Answer:

a. marginal analysis.

Explanation:

The cost to add the fried will be the cost added to obtain the fries rather than the cost of a single medium order of fries.

This is the basis of the marginal analysis on which the revenue and marginal cost represent the extra revenue granted for an additional unit and the extra cost for producing an unit. In theory, the firm produce when marginal revenue matches marginal cost.
