Hi Keshavraj!
We can review the questions as well as see which questions we have marked on the actual exam. But I dont think we can see that the question belongs to which topic.

SCJP 1.4<br />SCWCD 1.4

If you mean List interface when as you can guess interface has no implementation and there is no answer on your question.

But all implementation of java.util.List which are included in SCJP (ArrayList, LinkedList, Vector) allow "null" value to be added.
