Respuesta :
B) Pronoun-antecedent agreement error
Pronoun-antecedent agreement is when a pronoun agrees in usage with its antecedent.
If the noun is a subject noun, it must be replaced by a subject pronoun
If the noun is masculine, the pronoun should be masculine, and vice-versa
If the antecedent is a singular noun, it should be replaced by a singular pronoun
The sentence is not consistent in its use of pronouns to represent the subject.
The sentence starts by representing the pianist with the pronoun "They"
"The joys a pianist receives when they accompany a choir of singers........."
It proceeds in the remainder of the sentence by referring to the same pianist using the pronoun "her"
"....can make her years of practice and lessons all worthwhile."
This inconsistency in the use of pronoun can be referred to as Pronoun-antecedent agreement error
