A Use [Hookable(false)] as a method attribute. ✔ ✖
B Use [Wrappable(false)] as a method attribute. ✔ ✖
C Use [Replaceable(true)] as a method attribute. ✔ ✖
D Use a protected modifier. ✔ ✖

Correct Answer: Option B

Explanation

❌Incorrect. You can use ´[Hookable(false)] to block pre-events and post-events, but it doesn’t block extensions that are made by CoC. To prevent extensions that are made by CoC, use the ´[Wrappable(false)] attribute or the private modifier for the method.

✔️ Correct. ´[Wrappable(false)] generates a compiler error if CoC is your method. In this case, the project isn’t built because a compiler error exists.

✔️ Incorrect. ´[Replaceable(true)] allows you to overwrite the existing method and doesn’t generate a compiler error during build.
