D. Other goods and services given up in order to build the school

Explanation:

Opportunity cost refers to the expense that incurred when we're sacrificing one decision to choose another decision.

Government has a limited amount of budget. If the government choose to allocate that budget to build a school, it will automatically mean that the amount of money that can be used for other programs is reduced. This is why we can consider them as an opportunity cost.
