Explanation:

- Comply: This means to act in agreement with a command, request, rule, or law. It involves following directions or conforming to a standard.

- Option 1, Defer: This means to postpone or delay something. It can also mean to yield to someone else's judgment or authority. While related, it's not an antonym for comply because it's more about timing or hierarchy rather than agreement.

- Option 2, Consent: This means to agree or give permission for something to happen. It's similar in meaning to comply, as both involve agreement and approval.

- Option 3, Adhere: This means to stick firmly to a plan, rule, or belief. Like comply, it involves following or committing to an idea or rule, so it's not an antonym.

- Option 4, Oppose: This means to actively resist or refuse to comply with something. It's the act of standing against or resisting, making it the true antonym of comply.
