The correct answer choice is (B)

The conditions in the question stem establish a horizontal ZT block:

Because we have already established that Z can only be sold to the museum as either the second or third period piece, the block must be placed so that Z is from the second period and T is from the third period:

At this point, we can apply the first rule and third rules, which serve to establish that S is from the first period and that V is sold to the private collector:

The only remaining variables yet to be placed are Q and R. From the second rule we know that

and thus Q must be from the third period (otherwise it would violate the second rule). Consequently, Q must be sold to the private collector, and R, the random, occupies the museum’s first period:

Using this analysis, the problem is easy.

Answer choices (A), (C), (D), and (E): Each of these answer choices cannot occur, and therefore each is incorrect.

Answer choice (B): This is the correct answer choice.
