Answer:
Niacin (Ans. A)
Explanation:
Nicotinamide adenine dinucleotide (NAD) is known as important cofactor which help in carrying electrons from one reaction to another reaction in the cellular respiration process.
Cells are able to restore performed compounds which are containing a pyrimidine base precursor vitamin for the synthesis of NAD: nicotinamide, nicotinic acid, and nicotinamide riboside.
These elements are taken up from the diet whos containing vitamin B3. Nicotinamide, and nicotinamide riboside both can be absorbed from the gut. Niacin or vitamin B3 also produced within cells with the help of cellular digestion of NAD+.

Explanation:
<em>Hemophilia typically affects more males than females because the disorder is </em><em>X-linked </em><em>and </em><em>recessive</em><em>. </em>
<u>Females have two X chromosomes (XX) while males only have one X and one Y chromosome (XY). The two X chromosomes in females are capable of carrying alleles while the Y chromosome in males is hypothesized not able to carry alleles. </u>
Consequently, the two X chromosomes in females will both need to carry the recessive allele of hemophilia in order for any female to be affected for hemophilia while the males only need their single X chromosome to carry the recessive allele in order to be affected.
In order words, the presence of a single recessive allele is not enough for a female to be affected while it is more than enough for a male to be affected. Hence, more males are affected b hemophilia disorder than females.
