Assertion `:` Generally old people have hiher blood pressure.
Reason `:` Arterial diameter increases with Age.

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 assertion and reasoning question, we will follow these steps:

### Step 1: Analyze the Assertion
The assertion states that "Generally old people have higher blood pressure." This is a well-established fact in human physiology. As people age, various physiological changes occur, including an increase in blood pressure.

**Hint:** Consider the general trends observed in blood pressure as people age.

### Step 2: Analyze the Reason
The reason provided is "Arterial diameter increases with age." While it is true that certain changes in the arterial system occur with age, such as increased stiffness and potential changes in diameter, the primary factor contributing to higher blood pressure in older adults is not simply the increase in arterial diameter. Instead, it is often due to the stiffness of arteries and increased vascular resistance.

**Hint:** Think about the factors that contribute to blood pressure changes in older adults beyond just arterial diameter.

### Step 3: Determine the Relationship
Both the assertion and the reason are true statements. However, the reason does not correctly explain why older people generally have higher blood pressure. The increase in arterial diameter does not directly lead to higher blood pressure; rather, it is the stiffness and loss of elasticity in the arteries that contribute to this phenomenon.

**Hint:** Evaluate whether the reason logically supports the assertion.

### Step 4: Conclusion
Based on the analysis:
- The assertion is true: Old people generally have higher blood pressure.
- The reason is also true: Arterial diameter can increase with age.
- However, the reason does not adequately explain the assertion.

Thus, the correct answer is that both the assertion and reason are true, but the reason is not the correct explanation of the assertion.

### Final Answer
**Option B:** Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
