Assertion: Senescent phase of life ultimately leads to death.
Reason: There is progressive deterioration of body organs and their functioning.

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that the senescent phase of life ultimately leads to death. The senescent phase, also known as the aging phase, is characterized by a gradual decline in physiological functions and an increase in the likelihood of death.

2. **Understanding the Reason**: The reason provided states that there is progressive deterioration of body organs and their functioning during this phase. This means that as an organism ages, its organs and systems do not function as efficiently as they once did, leading to various health issues.

3. **Connecting Assertion and Reason**: The assertion and reason are connected. The deterioration of body organs and their functioning (the reason) is what leads to the ultimate outcome of death (the assertion). As organs fail to function properly, the overall health of the organism declines, which can result in death.

4. **Evaluating Truthfulness**: Both the assertion and the reason are true. The senescent phase does lead to death, and this is indeed due to the progressive deterioration of body organs and their functioning.

5. **Conclusion**: Therefore, both the assertion and the reason are true, and the reason correctly explains the assertion.

**Final Answer**: Both the assertion and reason are true, and the reason is the correct explanation of the assertion.
