D

Explanation:

Delivery costs are mixed and utilities are variable.

Variable costs are cost that changes in direct proportion to the level of production. This means that when the variable cost increases then more units are produced and decreases when less units are produced.

Mixed costs also known as semi-variable costs have properties of both fixed and variable costs due to the presence of both variable and fixed components in them.

In this case utilities is a variable cost, it increases as the units increase, while delivery cost is a mixed cost, it has the element of both fixed and variable.

A fixed cost does not change with the level of activity it remains the same.
