Aproduction possibilities curve deals with which of these concepts?

The answer to this question is opportunity costs
Opportunity costs refers to the total value that will be lost whenever you choose one decision over another.
For example, let's say that you have 10,000 dollars, which will be enough to produce either 100 tables or 150 chairs.
If you choose to use that money to produce 100 tables, the lost opportunity to produce 150 chairs is what called opportunity cost.

This would be a example of a "i want to be single person"
