  Show/Hide Explanation 

Correct Answer: A

Paintings: T, U, V, W, X, Y, and Z

To be chosen: 5

Condition:

  • If T is chosen, X cannot be chosen ⇒ T – X not together
  • If U is chosen, Y must also be chosen ⇒ U – Y together
  • If V is chosen, X must also be chosen ⇒ V – X together

If V is chosen:

Then X has to be there but if X has to be there then T cannot be there.

⇒ T is not chosen
