Answer 1

Hint: This question is about “Subject-Verb Concord”, i.e., the agreement of the verb used in the sentence with the subject. It refers to the proper usage of tenses on verbs as well as appropriate nouns/pronouns. The question is also an interrogative one, hence, proper pronouns are to be used as the interrogatives. While answering these types of questions, always keep in mind that the subject and the form of the verb must always be in an agreement to form a proper sentence.

Complete answer:
If we look at the given sentence, it is an interrogative sentence and asks the second person “You” the question about “seeing Amy ''. Also note that the action of “not knowing” is present. Hence, we can say that the solution has to be present perfect because the action has already been done and the inquiry is still going on.

Let us analyze the given options:
Option (A)- Have you seen- is correct as it is in present perfect, i.e., the required form of the verb as well as the required tense.
Option (B)- Did you see- is incorrect as it uses “did”, and describes the action being done in the past (Simple past tense). But the question states otherwise.
Option (C)- Had you seen- is incorrect as it uses “had”, and describes the tense as “past perfect”, but the given question is in the present tense.
Option (D)- Do you see- is incorrect as it is in simple present and describes the action as currently going on. But the question states otherwise.

Therefore the correct answer is option ‘A’.

Note: Few rules of Subject-verb Concord:
-The verb and subject must agree in number (singular or plural).
-Singular or a plural number of subjects will not change due towards/phrase in between the subject and verb. So be careful to find out the number of the particular subjects.
-Subjects that are joined by ‘and’ in a sentence use plural verbs.
