Explanation:
Humans have 23 pairs of chromosomes, or 46 individual chromosomes. Mutations in humans usually cause there to be a single extra chromosome, or a single missing chromosome.

D cannot be assumed as you cannot tell if there is uncontrolled cell growth. Therefore, the answer would be B.
That way they can get the average result and they're usually more accurate.
It can be concluded that both parents are also homozygous recessive for the gene
