Verified answer

Cuál really translates as "which". Here you have a choice of possibilities and you reach your decision.

You could have other such questions: "Who/which is the pretties girl in the class?" "Who/which is your favourite footballer?", etc., etc. where again it would be "cuál".

Qué is asking for information concerning the identity of "Las Rancheras". Here there is no question of having to select your answer from a range of possibilities: you are being asked to explain in a factual way. In other words, you are being asked: "who" or "what".

Cuál- which

Qué- what

cual is used for singular and que is used for plural

que means what

qual means which
