The students who __________ a top grade in pharmacology were admitted to postgraduate studies.Ahave receivedBhad receivedCreceiveDare receiving

To solve the question about which verb form fits best in the sentence, we can analyze the context:

1. Break Down the Problem

   • The sentence implies a past action where students who achieved top grades were granted admission. We need a past form of the verb.

2. Relevant Concepts

   • The verb tense must agree with the context: "were admitted" suggests the subject (students) completed the action before being admitted.

3. Analysis and Detail

   • A: "have received" is present perfect and suggests a connection to the present, which doesn't fit with "were admitted."
   • B: "had received" is past perfect, indicating that the grades were received before the admission occurred. This fits well with the context.
   • C: "receive" is simple present, which does not match the past context.
   • D: "are receiving" is present continuous and also does not fit the past context.

4. Verify and Summarize

   • The most fitting choice considering the timeline of events is "had received" (B).

Final Answer

The correct answer is B: had received.
