Assertion :- Advance stage of cancer shows contact inhibition.
Reason :- Property of contact inhibition forms cancer most dreaded condition.

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 Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are False.

Answer

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

### Step 1: Analyze the Assertion
The assertion states: "Advanced stage of cancer shows contact inhibition."
- **Contact inhibition** is a process where cells stop dividing when they come into contact with other cells. This is a normal mechanism in healthy cells to prevent overcrowding.
- In advanced stages of cancer, cancer cells often lose this property of contact inhibition, allowing them to continue proliferating uncontrollably. Therefore, the assertion is **false**.

### Step 2: Analyze the Reason
The reason states: "Property of contact inhibition forms cancer most dreaded condition."
- Contact inhibition is a mechanism that prevents excessive cell growth and division. In healthy tissues, this property helps maintain normal tissue architecture and prevents tumor formation.
- The statement implies that contact inhibition is related to the formation of cancer, which is misleading. In fact, the loss of contact inhibition is a characteristic of cancerous cells. Therefore, the reason is also **false**.

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

### Final Answer
The correct option is: **Both assertion and reason are false.**
