Best answer
Correct option is (b) Criss-cross inheritance

The best explanation: Colour-blindness is a sex-linked trait which shows criss-cross inheritance which means male transmits his trait to his grandson through his daughter, while a female transmits the traits to her granddaughter through her son.
