Answer:
The correct answer is letter "B": He is retiring, so he no longer has the trade-off of missing practice or a game.
Step-by-step explanation:
Trade-offs are the result of sacrificing one need to choose another option that fulfills a necessity as well. Trade-offs are the result of economic scarcity because individuals possess unlimited wants but the resources to fulfill those desires are limited.
Thus, if the quarterback is retiring he has plenty of time to move and will not have to sacrifice his game practices to do so.
