Question

1. what is the best answer to this question: ¿os gusta la comida?

no, no te gusta.
no, no nos gusta.
sí, sí me gusta.
no, nosotros no gustar comida.

Explanation:

The question ¿Os gusta la comida? is a Spanish question addressing a plural "you" (informal). The response must match the subject:

1. "No, no te gusta." uses singular "te", which does not match the plural question.
2. "No, no nos gusta." uses plural "nos" (we), which correctly responds to a plural "you" question with a first-person plural answer, and uses the correct verb form gusta.
3. "Sí, sí me gusta." uses singular "me", which does not match the plural question.
4. "No, nosotros no gustar comida." uses the incorrect verb form gustar instead of gusta.

Answer:

No, no nos gusta.
