Explanation:

- The word is “Subscribe,” which usually means to sign up for or agree to something—like a service or an idea.

- Option 1: ease — That means to make something less difficult or reduce effort. There’s no real connection or contrast to “subscribe.”

- Option 2: deny — Here’s the thing: “deny” is about refusing or rejecting something. If subscribing is saying yes or agreeing, denying is a pretty clear “no.”

- Option 3: diminish — This is about making something smaller or less important. It’s not really the opposite of subscribing—subscribing isn’t necessarily about increasing anything.

- Option 4: abate — To “abate” is to lessen or reduce, usually something negative like pain or a problem. No direct link to subscribing.

- So, the most appropriate antonym here is deny. It’s a direct opposite—you either accept (subscribe) or refuse (deny).

- Final answer:

- Option 2: deny
