The bony labyrinth of the internal ear is divided into three main areas. They are :

Options

A. vestibule, cochlea, perilymph
B. vestibule, saccule, utricle
C. vestibule, semicircular canals, tympanic membrane
D. vestibule, cochlea, semicircular canal

Explanation

**Step-by-Step Solution:**

1. **Understanding the Structure of the Ear**: The human ear is divided into three main parts: the outer ear, the middle ear, and the inner ear.

2. **Identifying the Inner Ear Components**: The inner ear contains the bony labyrinth, which is a complex structure responsible for hearing and balance.

3. **Dividing the Bony Labyrinth**: The bony labyrinth of the inner ear is divided into three main areas:
- **Vestibule**: This is the central part of the bony labyrinth and plays a role in balance.
- **Semicircular Canals**: Also referred to as semi-lunar canals, these structures are involved in detecting rotational movements and maintaining balance.
- **Cochlea**: This spiral-shaped structure is responsible for converting sound vibrations into neural signals for hearing.

4. **Conclusion**: Therefore, the three main areas of the bony labyrinth of the internal ear are the vestibule, semicircular canals, and cochlea.

**Final Answer**: The three main areas of the bony labyrinth of the internal ear are:
- Vestibule
- Semicircular Canals (Semi-lunar canals)
- Cochlea
