Blood fails to coagulate after an injury

The correct option is A:

Explanation of the correct option :

1. Hemophilia is sex linked recessive disorder.
2. It is a hereditary condition in which the body's capacity to induce blood clotting is impaired and as a result, people tend to bleed for longer after an injury and are more likely to experience bleeding into joints or brain.
3. Hemophilia is divided into two types: hemophilia A, which is caused by a lack of clotting factor VIII, and hemophilia B, which is caused by a lack of clotting factor IX.
4. Hemophilia is inherited from one's parents through a non-functional gene on the X-chromosome.
