Which of the following is NOT a sign of a healthy nail?

A sign of a healthy nail is characterized by attributes such as consistency in color, smooth texture, and resilience. When nails are healthy, they typically exhibit a uniform color with no discoloration or spots, maintain a smooth surface free of ridges and indentations, and possess enough strength to resist breaking or peeling under normal conditions.

Peeling or breaking indicates a lack of health, often due to factors such as dehydration, nutritional deficiencies, or exposure to harsh chemicals. Therefore, any manifestation of peeling or breaking is genuinely considered a negative sign reflecting the overall condition of the nail. This is why the choice indicating peeling or breaking is associated with unhealthy nails and is the correct response to the question.
