Answer:
b) false
Explanation:
Opportunity costs can also be viewed in terms of personal preferences or satisfaction. E.g. a person could legally work all day and all night. Of course no one can actually work that much, but it is possible to work between 16 - 18 hours per day. But by doing so, you will have to lose certain personal benefits like spending time with your family, girl/boy friend, doing things that entertain you, or even going to church if you are very religious (and many other things). People value their personal activities in a different way, and will decide what to do depending on which activity they value most.
