Twice in the Same Day, Carlos Used the Wrong Pronoun

Twice in the same day, Carlos used the wrong pronoun when asking questions. The first time, his friend Eric said that he was going to see the doctor, whom he finds quite competent. "Where is his office?" asked Carlos. Eric replied, "Her office is in the hospital annex." The second time, his niece Maya said that she liked her kindergarten teacher very much. "What's her name?" asked Carlos. Maya replied, "His name is Mr. Ngo." Both times, Carlos was embarrassed at his error. From a critical feminist point of view, which is the most likely explanation for Carlos' mistakes?

A) People lack an understanding of feminist theory.
B) Many types of work still have gender associations.
C) Education is a field that employees mostly women because of their nurturing qualities.
D) Liberal feminism has not had a significant impact on the medical field.
