Concept: This question tests your knowledge of the basic anatomy of the human ear, specifically the components of the outer ear.

Why (C) is correct: The outer ear is composed of two main parts: the pinna (also known as the auricle), which is the visible external part of the ear, and the external auditory meatus (or ear canal), which channels sound waves inward towards the eardrum.

Why other options are wrong:

A) Only pinna: This is incomplete as the external auditory meatus is also part of the outer ear.

B) Only external auditory meatus (ear canal): This is incomplete as the pinna is also part of the outer ear.

D) Pinna + Membranous labyrinth: The membranous labyrinth is a part of the inner ear, not the outer ear.

Common Mistake: Students sometimes confuse the parts of the outer, middle, and inner ear, especially the location of the labyrinth.

NEET Tip: Remember the ear is divided into three main parts: Outer, Middle, and Inner. The outer ear collects sound, the middle ear amplifies it, and the inner ear converts it into electrical signals and helps with balance.

Correct Answer: (C)
