The correct Answer is:
D

In case of complementary genes, the ratio of 9 : 7 is obtained in `F_(2)`-generation. This was first discovered by Bateson and Punnett.
Complementary genes are those genes which express themselves when present together. None of express themselves when present together. None of these two get expressed yourself when present alone.
