My answer is D: Elected officials will likely pay more attention to messages that come from a group of people.
My reasoning for this is that government officials usually pay attention to a group of like-minded people with the same opinions or etc. on a specific topic especially if the said group has interests in supporting them. It also the only option that makes the most sense, logically speaking.
Hope this helps! :)
The correct answer is retrieval
Explanation: Retrieval set means all the stores the person came into contact with, according to Oklahoma City Community College law.
In this sense, the stores she contacted are her own retrieval set.
