Answer:
The correct answer is A:
They have discussed the matter with each other.
Explanation:
The objective of collecting opinions from a number of people with regard to a particular subject such as performance evaluation or a hiring decision is to ensure that via the consideration of heterogeneous perspectives, the best decision is arrived at.
The very nature of collecting opinions from people who are most likely to view the subject from different unique perspectives requires that the subject be discussed. Hence, Option A cannot be a diluting factor.
