Whether to use te/le/les?

Question

Hi I am doing an exercise consisting of the following sentence and I have been given three options which I can use to fill in the blank in the sentence (te/le/les) and I dont know which is suitable. "?Qué te/le/les ha parecido el vestido a tu madre?" Could someone tell me which of the three options is suitable and why and also the trranslation of this sentence. I think it means " What did your mothers dress look like"? Thanks!

Answer 1

¿Qué te ha parecido el vestido a tu madre?= What did you think of the dress (referring to you and your mother at the same time????)

¿Qué le ha parecido el vestido a tu madre?= What did your mother think of the dress?

¿Qué les ha parecido el vestido a tu madre?= What did your mother think of the dress? (referring to your mother as "them" ?????)

Answer 2

,The answer is

Qué le ha parecido el vestido a tu madre?

Because this sentence can translate like this!

Qué le ha parecido el vestido a tu madre?= What did your mother think of the dress?

And other translate that is not really right sentence: What did you think of the dress(If we use the te!), What did your mother think of the dress?(If we use the les)
