Here is a question that I got wrong on PT #42. The correct answer puzzles me, so I am hoping someone can set me straight.

"For the school paper, five students--Jiang, Kramer, Lopez, Megregian, and O'Neill--each review one or more of exactly three plays: Sunset, Tamerlane, and Undulation, but do not review any other plays. The following conditions must apply:

Kramer and Lopez each review fewer of the plays the Megregian.

Neither Lopez nor Megregian reviews any play Jiang reviews.

Kramer and O'Neill both review Tamerlane.

Exactly two of the students review exactly the same play or plays as each other.

Which one of the following could be an accurate and complete list of the students who review only Sunset?

A) Lopez

B) O'Neill

C) Jiang, Lopez

D) Kramer, O'Neill

E) Lopez, Megregian"

The correct answer is (A), but I don't understand why it is not (C).

Sunset: Jiang

Tamerlane: Megregian, O'Neill, Kramer

Undulation: Megregian, O'Neill, Lopez

OR

Sunset: Megregian, O'Neill, Lopez

Tamerlane: Megregian, O'Neill, Kramer

Undulation: Jiang

In the first scenario, Jiang is the student who reviews ONLY Sunset. In the second scenario, Lopez is the student who reviews ONLY Sunset.

Why is this not correct?
