I am almost convinced this answer is wrong. Can anybody justify it as right?

Page 672, Question 46:
What's true about an entity bean's primary key?
A. Primary key fields must be cmp-fields.
...
...

I had checked this answer, but book says it is not because "you can use a compound key". But even with compound keys, the fields must still be cmp-fields right?

Right. My book lists A as one of the right answers for that question. Are you saying that yours doesn't?

No mine doesn't!! I am surprised because the book is of excellent quality otherwise.
