Assertion:The inner ear contains three ossicles (malleus, incus and stapes) which are attached to one another in a chain-like fashion.
Reason:The stapes is attached to the tympanic membrane and the malleus is attached to the oval window of the cochlea.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that the inner ear contains three ossicles (malleus, incus, and stapes) that are connected in a chain-like manner.
- **Evaluation**: This statement is incorrect because the ossicles are located in the middle ear, not the inner ear.

2. **Understanding the Reason**: The reason provided states that the stapes is attached to the tympanic membrane and the malleus is attached to the oval window of the cochlea.
- **Evaluation**: This statement is also incorrect. The malleus is actually attached to the tympanic membrane, while the stapes is attached to the oval window of the cochlea.

3. **Conclusion**: Since both the assertion and the reason are incorrect, we conclude that the correct option is that both the assertion and reason are false.

**Final Answer**: Both assertion and reason are false.
