At first, I thought this question would be very difficult. But each wrong answer is easy to eliminate if you use the rules. So take each rule and see what answers it eliminates.
Remember, the CDs in the answer choices refer to the first and second slots.
S needs to be before V (rule 1). So A is wrong.
The third rule proves B wrong. If W is after R, then W needs to be after both R and after T. In this answer W is only after R.
The second rule proves C wrong. T needs to be after both S and R. In this answer, T is only after S.
The third rule proves D wrong. W needs to be after T and R. In this answer, W is only after T.
I’ll admit that B, C and D are a little hard to visualize. The key is knowing that on B, for example, R and W are mentioned in rule 3, and so is T. Never let go of that idea. If an answer (e.g. B) mentions both R and W, you also need to ask where T can go while obeying the rule. Look at rule 3 until you see how the answer violates it, because if it mentions variables from a rule it almost certainly violates that rule. Draw sketches if they help visualize.
A lot of people look at an answer, say “oh, B mentions things from rule 3, interesting”, but then they let that thought drift out of their head. Always focus on the rules – if you make an observation, follow it till the end.
E is CORRECT. This diagram proves it is possible:
