Answer: the third option.

Reason: RRYy makes gametes RY and Ry; RrYY makes gametes RY and rY. A correct 4×4 representation duplicates those gametes as columns RY, RY, rY, rY and rows RY, Ry, RY, Ry (the third choice), which yields the four expected outcomes: RRYY, RrYY, RRYy, and RrYy each at 1/4.
