Answer

To determine where the Organ of Corti is found, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Organ of Corti**: The Organ of Corti is a crucial structure in the auditory system. It acts as the body's microphone, converting sound vibrations into neural signals.

2. **Identify its Location**: The Organ of Corti is located on the basilar membrane, which is part of the cochlea.

3. **Know the Parts of the Ear**: The ear is divided into three main parts:
- **External Ear**: This includes the outer structures like the pinna and the ear canal.
- **Middle Ear**: This contains the ossicles (tiny bones) and is responsible for transmitting sound vibrations from the outer ear to the inner ear.
- **Internal Ear**: This includes the cochlea and the vestibular system, which are responsible for hearing and balance.

4. **Locate the Cochlea**: The cochlea is situated in the internal ear. Since the Organ of Corti is found on the basilar membrane within the cochlea, it is also located in the internal ear.

5. **Select the Correct Option**: Based on the information gathered, the Organ of Corti is found in the internal ear. Therefore, the correct answer is:
- (a) Internal ear

### Final Answer:
The Organ of Corti is found in (a) Internal ear.
