Question

Read the claim and reason.

Claim: Our school cafeteria should offer more meatless main dishes.

Reason: There are a significant number of vegetarians attending our school.

What evidence best supports the student’s reason?

The results of a student survey suggest that twenty-three percent of the students consider themselves vegetarians.
Though school food is funded by state and county governments, the menu is determined by school cafeteria staff.
Salads and meatless pasta dishes add variety to school menus and provide vegetarians with possible choices.
Vegetarians rely on beans, nuts, and Greek yogurt as alternate sources of protein in their diets.

Answer 1

"The results of a student survey suggest that twenty-three percent of the students consider themselves vegetarians."

This directly gives a concrete, significant proportion of students who are vegetarian and thus supports the reason. The other choices don't provide evidence about how many students are vegetarian.
