Solution

The correct option is B

Carriers


In females, having a defective allele on the X-chromosome do not express the disorder, when the allele is recessive and the normal allele masks the activity of this allele. Males however having a single X chromosome, invariably expresses the disease, if they possess the defective allele. Since males get their X chromosome from the mother, the disease pedigree is from the carrier mother to her son.
