Verified step by step guidance

Step 1: Understand the anatomy of the ear, which is divided into three main parts: the outer ear, middle ear, and inner ear. The outer ear includes structures that collect sound waves and direct them toward the eardrum.

Step 2: Identify the components of the outer ear. The outer ear consists of the auricle (pinna) and the external auditory canal. The auricle is the visible part of the ear that helps funnel sound into the ear canal.

Step 3: Review the listed options: Cochlea, Auricle (pinna), Pharynx, and Stapes. Determine which of these structures belongs to the outer ear based on their anatomical location and function.

Step 4: Eliminate options that are not part of the outer ear. The cochlea is part of the inner ear, responsible for converting sound waves into nerve signals. The pharynx is part of the throat and not related to the ear's anatomy. The stapes is a bone in the middle ear that transmits sound vibrations to the inner ear.

Step 5: Confirm that the auricle (pinna) is the correct answer, as it is the primary structure of the outer ear responsible for collecting sound waves.
