Read the sentence.

Celebrities who help to raise awareness of significant world issues are more likely to have long-lasting bonds with their fans.

"who help to raise awareness of significant world issues"

needs a comma because it is a restrictive clause.
is correctly punctuated because it is a restrictive clause.
needs a comma because it is a nonrestrictive clause.
is correctly punctuated because it is a nonrestrictive clause.

Answer 1

I believe the answer is correctly punctuated because it is a restrictive clause. This is because the statement “who help to raise awareness of significant issues” narrows it down to talk about a specific group of celebrities; it is necessary to clarify.
