Explanation of Solution

Determine the variable that is not an input variable:

In the production of pizza, the amount of dough required to make the pizza, type of cheese required, and the oven’s temperature are input variables. Input variable is the type of variable, which would be under the control of the management.

When the pizza was delivered to the customers, the after process would not be an input variable. As time that the customer leaves the pizza in the refrigerator would occur after the customer purchases pizza, it is not an input variable.

Hence, option (d) is correct and options (a), (b), and (c) are incorrect variables.
