Valeria quiero ir de fiesta.
What do you recommend for dinner
D: ¿Te gusta vender los collares?
Gustar conjugated is still one word so it cannot be "gust a"
A verb ("vender") is singular so you cannot use "gustan"
A verb after gustar has to be infinitive
so the correct answer is ¿Te gusta vender los collares?
Why isn’t it in english lol we can’t read it unless it’s in english
