Answer: D. comemos (eat)
Since it’s about the cafeteria food in your school.
a. comen - would be used as eat as well but for two other people / Ex: Ellos (They) comen mucho (eat a lot).
b. escribimos - this means write but for yourself and other people / Ex: Nosotros (We) escribimos cada día (write every day).
c. escriben - same with comen. Means “they write” / Ellos (They) escriben en la pizarra (write in the board).
