What are common signs of a fungal infection in nails?

1. Peeling, cracking, and discoloration

2. Discoloration, thickening, and brittleness

3. Softness, lengthening, and fading

4. Shiny appearance and redness

The correct answer is: Discoloration, thickening, and brittleness

Common signs of a fungal infection in nails include discoloration, thickening, and brittleness. Discoloration often manifests as yellow, brown, or white spots under the nail, which can be a clear indication of a fungal issue. Thickening occurs as the fungal infection progresses, causing the nail to become unusually hard and elevated. Brittleness refers to the nails breaking, crumbling, or splitting easily, which is frequently observed with fungal infections. These symptoms can significantly affect the appearance and health of the nails, making them an important diagnostic factor in identifying fungal infections. Other options describe different conditions or effects that may not specifically indicate a fungal infection. For instance, peeling and cracking are often associated with dryness or trauma to the nails, while a shiny appearance and redness might suggest inflammation or irritation rather than a fungal issue. Understanding these signs is crucial for proper identification and treatment of nail infections.
