"Capitulate" means to give up resistance and surrender or agree to someone's demands. Its opposite must show refusing to give in.
- Option A, "Summarize": This means to give a short account of something, an action about speech, not about surrender or defiance.
- Option B, "Disobey": This means to refuse to follow an order, which is related but not a precise opposite of surrendering in a struggle or fight.
- Option C, "Resist": This means to stand firm and oppose, the direct opposite of giving up or surrendering, which is exactly what "capitulate" describes.
- Option D, "Deride": This means to mock or ridicule someone, which has no real connection to surrender or its opposite.
The correct choice is option C, "Resist".
