Question

translate to spanish:
they are going on vacation to the united states.
nosotros vamos de vacaciones a los estados unidos.
ellos van de vacaciones a los estados unidos.
vosotros vais de vacaciones a los estados unidos.

Explanation:

The original sentence refers to the third-person plural "They". "Nosotros" means "We", "Vosotros" is the informal second-person plural "You all", while "Ellos" correctly translates to "They" (masculine/gender-neutral plural) and the verb structure matches the meaning of "are going on vacation to the United States".

Answer:

Ellos van de vacaciones a los Estados Unidos.
