Concept:Emphatic stress is used when a speaker corrects a wrong detail in a question by emphasising the accurate word.
Explanation:The stressed word in the answer should replace an incorrect detail in the question.
Since the answer identifies Bimpe as the first to submit the assignment, the question must have suggested that someone else did it.
Option A presents Nneka as the wrong person.
Options B, C, and D do not change the person, so they cannot be corrected by stressing the name Bimpe.
Therefore, option A is the appropriate question to which the emphatic response is given.
Answer:A. Was Nneka the first to submit the assignment?
