Which use the boldfaced vocabulary word correctly? a. he obstinate them until they gave up. b. they were going obstinate when we showed up late. c. when the teacher attempted to discipline home, he was obstinate. d. the obstinate car drives smoothly and easily. with the answer

I believe the answer is C.) When the teacher attempted to discipline him, he was obstinate.

Obstinate means; “Stubbornly refusing to change ones opinions or chosen course of action, despite attempts to persuade one to do so.” The sentence states that the teacher is trying to discipline the boy, but he refuses to.

I hope this helps :))
