Ya its right.
How its possible for this gate.
The (OR) gate of first two input is (0 0) its output for (0).
Otherwise the NAND gate of output is complement of OR gate.
Its reverse process.

C output in or gate s = 1 bcom nor gate s = 0.
D output in or gate s = 0 bcom nor gate s = 1.
So answer s D.
D output in or gate s = 0 bcom nor gate s = 1.
So answer s D.

Option C is right or gate is inverse of nor gate.

OR gate operation is reverse of NOR gate.
