Statement Analysis:
- A and C are seated next to each other.
- A is seated two seats away from D.
- B is not seated next to A.

Conclusion:
- D is seated next to B.
- E is seated next to A.

Explanation:
Let's analyze each statement and determine the possibilities.

I. C is seated next to A:
Since A and C are seated next to each other, there are two possible arrangements: ACBDE or CBDEA.

II. A is seated two seats from D:
If A is two seats away from D, there are two possible arrangements: ACBDE or CBDEA.

III. B is not seated next to A:
This means that B cannot be seated next to A in any arrangement.

Now, let's analyze the options:

I. D is seated next to B:
Based on the given information, we cannot determine whether D is seated next to B or not. Therefore, this statement is not necessarily true.

II. E is seated next to A:
Based on the given information, we can see that in both possible arrangements (ACBDE or CBDEA), E is seated next to A. Therefore, this statement must be true.

Hence, the correct answer is option 'C' - Both I and II.
