What is the primary function of a cafeteria in a school?

The primary function of a cafeteria in a school is as a dining area where food is served. In this setting, students gather during lunch and sometimes breakfast to eat meals prepared by the school or catering service. Cafeterias are designed to accommodate large groups of students, providing a space that is conducive to casual dining. This area not only serves food but also fosters social interaction among students during meal times, playing a crucial role in the daily routines of the school environment.

Other functions often associated with school facilities, such as holding meetings or conducting after-school activities, typically occur in designated areas such as classrooms or auditoriums, rather than the cafeteria itself. Additionally, a dormitory would be a living space, not relevant to the function of the cafeteria. The focus remains on its role as a dining facility, which makes option C the correct answer.
