What causes leukonychia?

A type of injury
Strong chemicals
Dry cuticle
A contagious virus

The correct answer is: A type of injury

Leukonychia is a condition where white spots or streaks appear on the nails. These spots are usually harmless and are caused by injury or trauma to the nail matrix, which is the area where the nail grows from. This can be caused by factors such as biting or hitting the nails, as well as certain medical procedures like chemotherapy. Option B is incorrect because while strong chemicals can cause damage to the nails, they do not specifically cause leukonychia. Option C is incorrect because dry cuticles do not directly cause white spots on the nails. Option D is incorrect because leukonychia is not caused by a contagious virus, but rather by physical trauma to the nails.
