• A. Cradle cap
• B. Ringworm
• C. Impetigo
• D. Eczema

Answer: (A)

Cradle cap is the infant form of seborrheic dermatitis, showing up on the scalp as greasy, yellow scales and crusts that may involve the eyebrows or eyelids. It’s very common, benign, and usually fades on its own over several months. Gentle washing with a mild shampoo and a soft brush helps loosen the scales; most cases don’t require aggressive treatment, though medicated shampoos may be used under a clinician’s guidance if needed.

Why this fits best: the described scalp condition is characteristic of cradle cap. Ringworm would present as patchy scaly areas with possible hair loss and is fungal. Impetigo causes honey-colored crusts around the mouth or nose and is a bacterial infection. Eczema (atopic dermatitis) involves dry, red, itchy patches often in the cheeks or skin folds. These patterns differ from the greasy, scale-prone scalp of cradle cap.
