A. The team’s research found that people who regularly engage in physical activity, report a greater sense of wellbeing than people who don’t.
B. The team’s research found that people who regularly engage in physical activity, report a greater sense of wellbeing than people who don’t.
C. The team’s research found that people who regularly engage in physical activity report a greater sense of wellbeing, than people who don’t.
D. The team’s research found that people who regularly engage in physical activity report, a greater sense of wellbeing than people who don’t.

Correct Answer is: A

A comma is used to separate a nonessential clause from the rest of the sentence. A nonessential clause is a clause that can be removed from the sentence without affecting the grammatical coherence of the sentence. In this sentence, the clause "who regularly engage in physical activity" is a nonessential clause because it can be removed from the sentence without affecting the grammatical coherence of the sentence. Therefore, the comma should be placed after the nonessential clause.
