Answer:
B) It would increase the opportunity cost of becoming a broadcaster.
Explanation:
Opportunity costs are defined as the cost of choosing one alternative activity or investment over another. 
The basketball player has two options, he can continue to play for an NBA team with a much better salary, or he can decide to become a broadcaster. If the player decides to quit basketball, then he will lose more money due to pay raise. That amount of money that he will lose if he decides to become a broadcaster is the opportunity cost of becoming a broadcaster. Since the pay increase raised the player's salary, the opportunity cost of becoming a broadcaster also increases.
