The third alternative is correct (C).
The cost structure of a business is composed of fixed costs and variable costs. Fixed costs are those costs that can not be quickly eliminated, such as rent and taxes. Variable costs are those that accompany the rate of production or sale of the business, such as inputs and manpower.

In the case of the Gerda grocery store, it can reduce the number of hours of some workers, as described in alternative C.
