Hola! 😄
In these case, both sentences are wrong. The correct sentence would be:
A la meva filla li agrada l’anglès.
Another examples with this verb ->
A mi m’agrada la platja.
T’agrada la síndria?
Als meus pares els agrada la muntanya.
The verb “agradar” works different than normal verbs, in the way that the subject of the verb is the thing/object that is liked, instead of the person liking the thing/object.
This means that we conjugate the verb to the 3rd person singular if the liked object is one (agrada), or to the 3rd plural if there are more than one liked objects (agraden).
Moreover, since the liked object is the grammatical subject of the sentence, the person that likes becomes the Indirect Object of the verb, that is why we need to use the “a” preposition with it (A la meva filla).
You can think of it as if you’d say in English something like: “English is liked by my daugther”. Hope that it helps! 👍☺️
