Explanation:

Let’s break it down:

- Statement I: D finished after C and E but before A and B.

- That tells us the partial order: C/E, D, A/B (but who is before who among C and E? Same question for A and B? Not clear.)

- Statement II: There were two people between E and A.

- That gives us options for how they might be spaced, but tells us nothing about the exact order for everyone else.

- Using both together: You can build possible arrangements, but you’ll still have multiple possible winners depending on whether C or E comes first and where everyone else falls.

Options:

1. Either I or II alone, but not the other, is sufficient – that’s out.

2. Both I or II alone are each sufficient – not even close.

3. Only both together are sufficient – nope, still can’t pin down the winner with certainty.

4. Need more info – This is it. There’s not enough to declare a clear winner.
