Question

I _____ my course by that time.

• A. will complete
• B. had completed
• C. completed
• D. shall have completed

Answer 1

Answer:

D. shall have completed

• The phrase “by that time” points to an action that will be finished before a specific future moment.

• For this, we use Future Perfect Tense:
  shall/will have + past participle.

• Here: shall have completed (or will have completed) is correct
