Ophthalmologist : _____ :: Dermatologist: skin

Eyes

Ophthalmologist : Eyes :: Dermatologist: Skin

The correct answer is Eyes.

An ophthalmologist is a doctor who specializes in eye care, while a dermatologist is a doctor who specializes in skin care. Therefore, the correct analogy is between ophthalmologists and eyes, and dermatologists and skin.

The other options are not as closely related to ophthalmology and dermatology:

• Children are not a specific area of specialization in medicine.
• Bones are treated by orthopedists.
• Ears are treated by otolaryngologists.
