Hi, this comes down to figuring out what the new condition means. We know that S is between p and l from the final rule, so if s is before p, s must be after l. So, the order would be l s p.

This also means that l and s cannot go last, and since none of h v or r can go last, p must go last. We know that p must be next to v or s, and since v must have two things after it, s must be next to p, so we have

_ _ _ _ S P

This knocks out B D and E, and we know that C isn't possible since there would not be room for the other two that must follow V, so we are left with A.
