ExplanationA is matched with 2: Haemophilia is a genetic disease caused by mutations in clotting genes.It is inherited via X chromosome.Under this, blood does not clot properly due to a deficiency of clotting factors (such as Factor VIII in Haemophilia A or Factor IX in Haemophilia B).This leads to excessive bleeding even from minor injuries.B is matched with 3: Diabetes is primarily a hormonal disorder related to insulin production or the body’s inability to use insulin effectively.Type 1 diabetes is due to insufficient insulin production (autoimmune) while Type 2 is due to insulin resistance.C is matched with 1: Rickets is caused by a deficiency of vitamin D, calcium, or phosphate, leading to weakened bones.It is not genetic or hormonal but results from nutritional deficiencies.D is matched with 4: Ringworm is a fungal infection caused by dermatophytes, affecting skin, hair, nails resulting in ring- shaped patches.483
