If P and H are together, then they must be on the second or third shelves (we can’t both fit on the first).
F must be on the other shelf, because F needs an open space to go with a novel. There are two ways this could go:
In the first case, V has to go in second, because F needs to go with a novel.
In the second case, V and S are interchangeable. F already has W, so the novel requirement is satisfied (W can’t fit anywhere else.)
A is wrong because P could go in 2.
B is wrong because in the 2nd case, V goes in 3.
C is wrong because S can go in 1 or 3 in the second scenario.
D is wrong because S could go in 3 in the second scenario.
E is CORRECT. In both scenarios there is no space for W to go anywhere else.
