The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Structure of the Ear:** - The ear is divided into three main parts: the external ear, the middle ear, and the inner ear. The cochlea is located in the inner ear. 2. **Identifying the Components of the Cochlea:** - The cochlea is a coiled structure that contains three main chambers: Scala Vestibuli, Scala Media, and Scala Tympani. 3. **Differentiating Between the Chambers:** - The Scala Vestibuli and Scala Tympani are part of the bony labyrinth, while the Scala Media is part of the membranous labyrinth. 4. **Understanding the Fluids in the Cochlea:** - The fluid in the Scala Vestibuli and Scala Tympani (bony labyrinth) is called perilymph. - The fluid in the Scala Media (membranous labyrinth) is called endolymph. 5. **Eliminating Incorrect Options:** - The question presents options that include perilymph, endolymph, and aqueous humor. Aqueous humor is related to the eye, not the ear, so it can be eliminated. - The cochlea contains both perilymph and endolymph, thus options stating only one of these fluids are also incorrect. 6. **Conclusion:** - The cochlea contains both perilymph and endolymph, making the correct answer the combination of both fluids present in the cochlea. **Final Answer:** The cochlea of the ear contains both perilymph and endolymph. ---
