Question

imagine how college sports will change in this century if inventions and coaching techniques​ __________ even more technologically sophisticated. A. will be B. become C. becomes D. became

Answer 1

A. will be ? I believe.

Answer 2

B: become

Step-by-step explanation:

The option that completes the sentence is B, with the verb become. There is a possible future action ("college sports will change"), and the reference to this action is in the present tense in the if-clause ("if inventions and coaching techniques become even more technologically sophisticated.") If means that the present action may or not happen.
