(C) Color blindness is an $X$-linked recessive disorder.Let the genotype of the color-blind man be $X^cY$ and the normal woman be $XX$.When they cross: $X^cY 	imes XX$.The possible offspring genotypes are $X^cX$ (carrier daughter) and $XY$ (normal son).Since the father passes his $X$ chromosome to his daughters and his $Y$ chromosome to his sons,all daughters will be carriers (phenotypically normal) and all sons will be normal.However,in the given options,the most accurate description of the phenotype is that all offspring are phenotypically normal (though daughters are carriers).
