The sentence has an incorrect shift in pronoun-antecedent agreement is letter (D) An apprentice can learn how to do a trade from their master. The subject of the sentence is "an apprentice." The apprentice can either be a girl or a boy. As usual, by default man has higher hierarchy over woman. The pronoun should be used is not 'their' but 'his'.
The sentence with a pronoun error is the following one: An apprentice can learn how to do a trade from their master. The subject of the sentence, "An apprentice" is singular and should be matched with a singular pronoun--"his" or "her" instead of "their." The sentence should read, "An apprentice can learn how to do a trade from his master."
so your answer would be D
