From the spec page no:48
The entity, its primary key, and its remote reference survive the crash of the EJB Container. If the state of an entity was being updated by a transaction at the time the container crashed, the entity�s state is automatically reset to the state of the last committed transaction. The crash is not fully transparent to the client�the client may receive an exception if it calls an entity in a container that has experienced a crash.


So, I too think, the answer is d,e

Once the client terminates, the session Bean terminates. In case of an EJB server crash, all session Beans are destroyed. But, Entity beans can survive EJB server crashes. Any EJB server crash is always transparent to the client.
 
I agree. Here's the link: http://aspose.com/file-tools
