A developer is using a Sling Model to apply some business logic to the values stored in the JCR before outputting them to the page, and all injected…

In Sling Models, the @DefaultInjectionStrategy annotation is used to specify the strategy for injecting

fields into the model. When setting it to DefaultInjectionStrategy.OPTIONAL, it indicates that all

injected fields in the Sling Model are optional and the model will not fail to instantiate if a field

cannot be injected. This is a class-level annotation that affects the default injection behavior of all

fields within the Sling Model.

Option B is incorrect because requiredInjectionStrategy is not a valid annotation property in Sling

Models.

Option C is incorrect because injectionStrategy is not specified at the class level; it is used on the field

level with the @Inject annotation.
