(d) If both the assertion and reason are false
(e) If the assertion is false but reason is true
Assertion : Saline water in not given to patients of hypertension.
Reason : Saline water can cause vomiting and may drop blood pressure suddenly causing cardiac arrest.

Explanation

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

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "saline water is not given to patients of hypertension."
- This is true because patients with hypertension (high blood pressure) are advised to avoid high salt intake, which is present in saline water.

2. **Understanding the Reason**:
- The reason states that "saline water can cause vomiting and may drop blood pressure suddenly causing cardiac arrest."
- This statement is misleading. While saline water can cause vomiting, it does not drop blood pressure; rather, it can increase blood pressure due to its salt content.

3. **Evaluating the Truth of Each Statement**:
- The assertion is true: Saline water is indeed not given to patients with hypertension.
- The reason is false: Saline water does not drop blood pressure; it can actually increase it.

4. **Conclusion**:
- Since the assertion is true and the reason is false, the correct option is (c): "If the assertion is true but the reason is false."

### Final Answer:
The correct option is (c) If the assertion is true but the reason is false.
