Which two scenarios require an Apex method to be called imperatively from a Lightning web component? Choose 2 answer

While a method making a web service callout must be called imperatively, the fundamental technical reason is that such methods cannot be `cacheable=true`; thus, option B provides the more general and direct underlying cause.

An Apex method must be invoked imperatively if it is not annotated with `@AuraEnabled(cacheable=true)`, because the `@wire` service requires methods to be cacheable for declarative data provisioning.

Calling a method with a button click is a common *trigger* for imperative invocation, but it is not the underlying technical *characteristic* of the Apex method itself that necessitates the imperative call. (Methods called this way are often not `cacheable=true`, fitting option B).

An Apex method needs imperative invocation when its execution is not automatically tied to the Lightning web component's initial rendering or reactive property changes, implying it is 'external' to the component's standard data-binding lifecycle and is invoked for specific actions or custom logic.
