The correct option is D Son suffers from colour blindness while the daughter does not suffer from it

Males only have one X chromosome, they have no spare normal chromosome to override the chromosome which carries the mutation.
If a mother is suffering from Red/green colour blindness, then it gets passed from mother to son on 23rd chromosome which is sex chromosome.
