What nail disorder is characterized by horizontal wavy ridges?

Leukonychia
Corrugations
Onychorrhexis
Furrows

The correct answer is: Corrugations

Answer Corrugations is the correct option as it specifically refers to horizontal wavy ridges on the nails. Option A, Leukonychia, refers to white spots or discoloration on the nails and does not match the description of horizontal wavy ridges. Option C, Onychorrhexis, refers to brittle nails with longitudinal ridges, not horizontal wavy ridges. Similarly, option D, Furrows, refers to vertical lines or grooves on the nails rather than horizontal wavy ridges. Therefore, B is the most appropriate option as it is the only one that accurately describes the given nail disorder.
