Answer:
Option A, Misunderstanding: The diet fad is safe. Reason: Technical jargon has been removed or simplified.
Explanation:
In this question, the scientist must have been allowed to explain the cause of "not being able to prove that diet fad causes heart attacks" instead of just answering "No, of course not." A hypothesis is a situational scenario which deals with "if" and "then" conditional scenarios.
