A is correct. CIW and the relevant anti-spam standards require that every bulk commercial email include a clear, functional opt-out mechanism so recipients can unsubscribe at any time, and this applies even when the user originally opted in via a checkbox on your registration page.

Hiroshi is right on the opt-out requirement, but worth adding that the unsubscribe mechanism has to actually work within a reasonable timeframe, not just exist as a link that bounces or takes 30 days to process, which is a detail the exam will sometimes test on.

The checkbox opt-in on the registration page is a good sign someone did their homework, but it does not get you off the hook forever. Every bulk message you send must include a clear way for subscribers to say "stop sending me this," which is A, because CAN-SPAM and basic permission marketing both require an unsubscribe mechanism in every single message, not just the first one.

Option B tripped me up for a second because sharing opt-in lists with "related companies" sounds like something real companies do, but that is exactly the kind of move that gets you flagged as spam and violates CAN-SPAM rules. Spin up a test campaign in Mailchimp's free tier and you will see it forces you to include an unsubscribe link before it even lets you send, which is why A is the answer you need.
