I have taken the following from the specification as-is:
- If two entity objects have the same home AND the same primary key, they are considered identical.
- A client can
test whether two entity object references refer to the same entity object by using the isIdentical method. Alternatively, if a client obtains two entity object references from the same home, it can determine if they refer to the same entity by comparing their primary keys using the equals method.
-The result of comparing two object references using the
Java programming language Object.equals(Object obj) method is unspecified. Therefore, a client should always use the isIdentical method to determine if two entity object references refer to the same entity object.
now considering all the above since the question says - select only 1 option, "c" would be my BEST bet, and if given to select 2nd option, that would be "a".
What say?
