Assertion`:-` Calcified cartilage is the strongest cartilage.
Reason `:-` Calcified cartilage is formed by the calcification of elastic cartilage.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertiion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are False

Explanation

To solve the question, we need to evaluate both the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states that "Calcified cartilage is the strongest cartilage."

- **Evaluation**: This statement is incorrect. While calcified cartilage is indeed hard due to the presence of calcium deposits, it is not considered the strongest type of cartilage. The strongest cartilage is known as white fibrous cartilage (or fibrocartilage), which is made up of dense collagen fibers and provides great tensile strength.

### Step 2: Analyze the Reason
The reason states that "Calcified cartilage is formed by the calcification of elastic cartilage."

- **Evaluation**: This statement is also incorrect. Calcified cartilage is not formed from the calcification of elastic cartilage. Instead, it is typically formed from the calcification of hyaline cartilage. In certain areas of the body, such as in the pubis bone of frogs, hyaline cartilage undergoes calcification to become calcified cartilage.

### Step 3: Conclusion
Since both the assertion and the reason are incorrect, we conclude that the correct answer is that both the assertion and the reason are false.

### Final Answer:
Both the assertion and the reason are false.
