Answer:
B everyone's resources are limited
Explanation:
A trade-off will involve selecting one option from a variety of choices. In a trade-off, one has to forfeit one alternative to enjoy the other. A trade-off is the same as the opportunity cost. The cost of trade-off is expressed as the foregone benefit from the next best alternative.
A trade-off exists because people have to choose the best way to use their limited resources to satisfy unending needs. The few available resources, including time and money, cannot satisfy individuals' and households' needs and wants. People have to prioritize their needs and allocate resources accordingly. Both individuals and firms will often decide to cater to their most pressing needs first. By making those decisions, a  trade-off is created.
