does 'Los estudiantes' go with 'estudian' or 'estudiamos'?

Question

Los estudiantes _____________ la clase de español. (estudiar)

Answer 1

estudian

The subject, estudiantes, can be replaced with the subject pronoun ellos (they) so that is the correct verb form.

Estudiamos should only be used to say "we study".

Answer 2

Since it is los estudiantes is in the plural form, representing "they" it would be estudian not estudiamos(for we)

Answer 3

If I'm one of the students I would say "estudiamos". From the looks of this sentence, I would guess that we're talking about a group that does not include me--so "estudian".

"Como estudiantes, estudiamos español todos los días."

"Aquellos estudiantes estudian español todos los días."
