Select the most appropriate option to fill in blank number 2.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. will be.
"Will be" is a future passive construction, which implies that the teachers are expected to do something (i.e., participate in CPD opportunities) as part of their professional responsibilities.
The sentence is setting up a clear future obligation for the teachers, meaning they are expected to participate in CPD (Continuing Professional Development) hours every year, and "will be" expresses this expectation.
