Solution
The correct option is B Christmas disease
In haemophilia, the blood does not clot as it should. Haemophilia is normally an inherited disorder. It happens because of a defect in one of the clotting factor genes on the X chromosome. Haemophilia tends to occur in males since the gene can be passed from mother to son. Males typically lack a second X chromosome so they are unable to make up for the defective gene. Most females have XX sex chromosomes while most males have XY sex chromosomes.Haemophilia B, also known as "Christmas disease," occurs when a person lacks clotting factor IX.So, the correct answer is 'Christmas disease'.
