Explanation

Haemophilia is a hereditary genetic disorder that impairs the bodys ability to control blood clotting. It is caused by a deficiency or absence of specific clotting factors, which are proteins in the blood needed to stop bleeding. Consequently, even a minor injury can lead to prolonged bleeding because the blood fails to clot normally. This makes option D the correct answer. It does not primarily affect hemoglobin levels, white blood cells, or cause rheumatic heart disease.
