What is a common sign of fungal infection in nails?

• A. Severe brittleness
• B. Change in nail color and thickness
• C. Increased shine of the nails
• D. Growth spurts

Answer: (B)

A common sign of a fungal infection in the nails is a change in nail color and thickness. Fungal infections can cause nails to become discolored, often appearing yellow, green, or brown, and can also lead to thickening or crumbling of the nail plate. This is due to the infection disrupting the normal structure of the nail. As the fungal infection progresses, it can cause the nail to separate from the nail bed, resulting in further changes in appearance and texture.

Severe brittleness might also be associated with nail issues, but it is not a primary indicator of fungal infection. Increased shine of the nails usually indicates healthy nails, while growth spurts are not typically related to the presence or severity of fungal infections. Therefore, the most reliable and recognizable sign among the options provided is the change in nail color and thickness.
