Which disease causes excess swelling of the legs?

Correct option is D

The correct answer is (d) Elephantiasis.
· Elephantiasis, also known as lymphatic filariasis, is a parasitic disease caused by microscopic, thread-like worms.
· The infection is spread by mosquitoes and can lead to severe swelling, especially in the legs, due to lymphatic system blockage.
· This swelling, known as lymphedema, can cause the skin to become thickened and hardened, resembling the skin of an elephant, which is how the disease gets its name.

· Cholera: An infectious disease causing severe diarrhea and dehydration.
· Tuberculosis: A bacterial infection that primarily affects the lungs, though it can affect other parts of the body.
· Leprosy: A chronic infectious disease caused by Mycobacterium leprae, leading to skin lesions and nerve damage, but not specifically associated with leg swelling like elephantiasis.
