Answer:
Option A, 1/64
Explanation:
The genotype of a carrier female would be Pp
The genotype of a carrier male would be Pp
When these two adults are crossed , the following offspring are produced
Pp x Pp
PP, Pp, Pp, pp
Thus out of four children 3 children have normal phenotype but two are carrier.
So probability of having one normal child (with genotype PP) is 
So the probability of three normal children is
Hence, option A is correct
