Answer:
had received
Step-by-step explanation:
'Receive' is not in the correct tense that is used in the sentence above, as it is in present tense, while the sentence described is in past tense. This automatically eliminates answers 'A. receive' and 'D. had receive.' The specific word ' had' implies that it had occurred already, and sounding it aloud/reading aloud will make more sense and sounds better.
