Question

Fill in the blank with the most appropriate word.

I would _____ him if I had seen him in time.

• A. tell
• B. have told
• C. told
• D. had told

Answer 1

Answer: (B)

The sentence refers to an action which did not actually happen(telling him) because something else did not happen at first(seeing him in time). Hence, "would have", that is, future perfect+past participle of the verb (told) should be used. Hence, Option B is correct. The rest of the options do not adhere to this rule, hence, incorrect.
