Question

Which sentence is grammatically correct? (*Hint- think about the “personal a” rules.)

Answer 1

The option A.)"Vistamos a los abuelos" is correct. "Vistamos" is signifying the action and "a los abuelos" is just a more proper way to show who the action is being done towards.

Answer 2

Visitamos a los abuelos. - We visit the grandparents.

Why?

Visitamos los abuelos is an incomplete sentence in Spanish.

A los abuelos visitamos is not proper Spanish at all.

This is the reason Visitamos a los abuelos is correct.

Hope this helps!~
