Answer:
A. " … fought and argued … "
Explanation:
To be stubborn is to be obstinate, is equal to refusing to move or to change one's opinion on something or attitude regardless of the existence of good arguments or reasons to do so. People who are stubborn are often difficult to treat or handle for their sometimes unreasonable resistance, and they often fight and argue, in order to defend their point of view or to prove that their position is the best. So " … fought and argued … " is one context clue that helps us infer the character's stubbornness.
