Answer:
b.) The team's costs to increase
Step-by-step explanation:
Nominally, revenues will be the same in Canadian dollars, because the Canandian dollar has become weaker against the U.S. dollar, but that does not necessarily mean that it has lost value in Canada itself.
However, now the NHL team will have to change more Canadian dollars for the same amount of U.S. dollars in order to pay its players, causing the team's wage costs to rise.
