You can specify resources that are needed by the bean in the deployment descriptor using env-ref, ejb-ref, or resource-ref elements.

Besides those three elements, depending on the resource type, resource-env-ref, message-destination-ref, persistence-unit-ref, and persistence-context-ref may also be used to inject resources. Is that not correct?

The option says, "It is possible to inject resources into a bean without using annotations. ", which is correct.
The explanation is merely trying to providing examples of how that can be done. It has now been enhanced to make that clear.

thank you for your feedback!

the explanation of the correct answer(option 5) says that:
You can specify resources that are needed by the bean in the deployment descriptor using elements such as env-ref, ejb-ref, or resource-ref elements

i doubt there is such element as env-ref. are you talking about env-entry ?

Yes, it should be env-entry. This has now been fixed.
