The rules are correct, but the placement of the elements on the diagram is not correct.

Thanks for catching that. I, unfortunately, have no way to access or change that image, but here's a quick explanation.

The condition starts us off with T in 1 and Y in 4.
We should write those in,
T __ __ Y __ __ __
and then ask ourselves about T, Y, and spots 1 and 4 in the rules.

T - S tells us nothing, since if T is in 1, S will automatically be after T.
Y is not 7th tells us nothing, because we already know Y is 4th.
The last rule talks about P being 1st, and since we know that P is not 1st, we know that Y is NOT before V.

Hence, we know for this problem that it's V - Y.
We also know that S is in one of the first three spots, so S and V will be occupying spots 2 and 3.

T (S, V) Y __ __ __

Who's left?
P - W and Z

So we could write that as
T (S, V) Y (Z, P - W)

(A) Not mandatory. P could be 5th
(B) Not mandatory. S could be 3rd
(C) Yes. V is either 2 or 3, so it's no later than 3rd.
(D) Not mandatory. W could be 6th
(E) Not mandatory. Z could be 5th.
