Complete Question Explanation

The correct answer choice is (D).

The question stem specifies that neither X nor V confess. Thus, neither X nor V can be questioned on day five. And, because Z cannot be questioned on day five, we can infer that Y must be questioned on day five. This establishes that Y must confess, and therefore answer choice (D) is correct.

For the remaining answer choices:

T is questioned third and either can confess or not confess, and thus answer choice (A) does not have to be true and is incorrect.

Z must be questioned first, and then X and V must be questioned on days two and four, not necessarily in that order. Thus, answer choices (B) and (C) do not have to be true and are incorrect.

Although Z must be questioned first, the suspect questioned first can either confess or not confess. Thus, answer choice (E) does not have to be true and is incorrect.
