genetic disorder where there is an absence of proteins needed for blood clotting.
A
anemia
B
hemophilia
C
leukemia
D
atherosclerosis
Explanation: 

Detailed explanation-1: -Hemophilia is caused by a mutation or change, in one of the genes, that provides instructions for making the clotting factor proteins needed to form a blood clot. This change or mutation can prevent the clotting protein from working properly or to be missing altogether. These genes are located on the X chromosome.

Detailed explanation-2: -In people with hemophilia, there is a mutation (difference from normal) in either the gene for the factor VIII protein or the gene for the factor IX protein. The mutation causes the body to produce too little factor VIII or IX.

Detailed explanation-3: -Hemophilia A is a hereditary bleeding disorder caused by a lack of blood clotting factor VIII. Without enough factor VIII, the blood cannot clot properly to control bleeding.

Detailed explanation-4: -Hemophilia is a rare disorder in which the blood doesn’t clot in the typical way because it doesn’t have enough blood-clotting proteins (clotting factors). If you have hemophilia, you might bleed for a longer time after an injury than you would if your blood clotted properly.

Detailed explanation-5: -Hemophilia B is a rare genetic bleeding disorder in which affected individuals have insufficient levels of a blood protein called factor IX. Factor IX is a clotting factor. Clotting factors are specialized proteins needed for blood clotting, the process by which blood seals a wound to stop bleeding and promote healing.
