Great job eliminating A and C! I can walk you through eliminating B and E.
For answer B, S can't transmit to R, because the same computer has to transmit to both R and S (see rule 3).
For answer E, P would also have to transmit to S, because of rule 3. But there would then be no computer left for S to transmit the virus to, which would violate rule 2. So, E can't be correct.
I hope that helps!
