Who is most likely to be affected by hemophilia?

Hemophilia is a genetic disorder that affects the body's ability to clot blood due to the absence or defect of clotting factors. It is typically inherited in an X-linked recessive pattern, primarily affecting males. Individuals with hemophilia have a congenital anomaly, which means that they are born with the condition. This congenital anomaly specifically affects the blood clotting mechanism, leading to prolonged bleeding or difficulty in stopping bleeding after injuries.

The other options describe various health conditions, but they do not specifically relate to the genetic and hereditary nature of hemophilia. For instance, a viral infection, autoimmune disease, or chronic fatigue syndrome may lead to various health complications but are not directly linked to the inherent clotting issues seen in hemophilia. Therefore, a person with a congenital anomaly affecting clotting is directly associated with the characteristics of hemophilia, making it the most likely scenario to affect someone with the disorder.
