A. Didn’t see
B. Haven’t seen
C. Hadn’t seen
D. None of these

Answer 1

Hint: Verb tenses tells us how an action relates to the flow of time. There are three main verb tenses: present, past and future.

Complete step by step answer:
Present perfect tense is used in this question. Present perfect tense is used to indicate a link between the present and the past.
The given sentence is in present perfect tense. This tense refers to an action that began in the past and has continued up till now. Such sentences takes the form of Subject + has/have + V3(participle) +Object
Option A) Didn’t see – is an incorrect answer because the verb “see” does not agree with the tense of the statement. Hence, this is the wrong option.
Option B) Haven’t seen - is the correct answer because the verb 'seen' agrees with the tense of the sentence. The present perfect auxiliary verb 'have' agrees with the subject, which is first person singular. Thus, this is the correct answer.
Option C) Hadn’t seen – is an incorrect answer because as the auxiliary verb is in past perfect tense and we need the answer in the present perfect tense. Thus, this is an incorrect answer.
Option D) None of the above – this option is void.
I haven’t seen him since we met a year ago.

So, the correct answer is “Option B”.

Note:
In such sentences it is important to understand the present perfect tense. The present perfect tense is composed of two elements i.e. the appropriate form of auxiliary verb to have (present tense) plus the past participle of the main verb. (The past participle of main verb base + ed = based). Thus, we have to make sure that we use the tenses in the correct way and make our sentence grammatically correct.
