Suggested Answer:

Box 1: [Hookable(true)]
If a method is hookable, extenders can subscribe to pre-events and post-events.
For public methods, you can opt out by adding [Hookable(false)] to the method.
You can opt in for private and protected methods by adding [Hookable(true)] to the method.
If a method is explicitly marked as [Hookable(false)], then it is not wrappable.
Box 2: [Wrappable(false)]
If a method is wrappable, extenders can wrap it by using Chain of Command (CoC). Extenders must call next, because they aren't allowed to break the CoC.
For protected and public methods, you can opt out by adding [Wrappable(false)] to the method.
Box 3: [Replaceable]
If a method is replaceable, extenders can wrap it by using CoC, but they don't have to unconditionally call next. Although extenders can break the CoC, the expectation is that they will only conditionally break it. The compiler doesn't enforce calls to next.
To be replaceable, a method must also be wrappable.
For wrappable methods, you can opt in by adding [Replaceable] to the method.

Correct 1) [Hookable(true)] If a method is hookable, extenders can subscribe to pre-events and post-events. 2) [Wrappable(false)] If a method is wrappable, extenders can wrap it by using Chain of Command (CoC). Extenders must call next, because they aren't allowed to break the CoC. 3) [Replaceable] If a method is replaceable, extenders can wrap it by using CoC, but they don't have to unconditionally call next. https://learn.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/extensibility/extensibility-attributes

hookable not hooktable and option correct answer [hookable(false)] If a method is explicitly marked as [Hookable(false)], then it is not wrappable. look this url https://learn.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/extensibility/extensibility-attributes If a method is explicitly marked as [Hookable(false)], then it is not wrappable.
