"They travel a lot."
Translation:Ils voyagent beaucoup.
ils is plural and il is he, singular, the answer should be ils/elles because it is plural!
Elles is for a group of females. Ils is for a group of males or mixed genders.

they can be translated as "Nous" or "Ils" or "Elles". I used Nous and I think my translation is also correct.
