Answer :
B. Coach because it is used as a title/name and proper noun in this sentence
B. Coach
In this particular context, it sounds like "Coach" is a title, and a replacement for a name. Under these circumstances, we would capitalize it.
If we were referring to "a coach" or "the coach", then it would not be capitalized.
