Assertion (A) Ranitidine is used to treat hyperacidity and brompheniramine is used to treat hyperallergy .
Reason (R ) Both of these drugs are antihistamines.

Options

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

Answer

To solve the question, we need to analyze both the assertion (A) and the reason (R) provided:

**Assertion (A):** Ranitidine is used to treat hyperacidity and brompheniramine is used to treat hyperallergy.

**Reason (R):** Both of these drugs are antihistamines.

### Step-by-Step Solution:

1. **Understanding Ranitidine:**
- Ranitidine is classified as an H2 antihistamine. It works by blocking H2 receptors in the stomach lining, which reduces the production of stomach acid. This makes it effective for treating conditions related to hyperacidity, such as gastroesophageal reflux disease (GERD) and peptic ulcers.

2. **Understanding Brompheniramine:**
- Brompheniramine is classified as an H1 antihistamine. It is primarily used to relieve symptoms of allergy, such as runny nose, sneezing, and itching. H1 antihistamines block the action of histamine at the H1 receptor sites, which is why they are effective in treating allergic reactions.

3. **Evaluating the Assertion:**
- The assertion states that ranitidine is used for hyperacidity and brompheniramine is used for hyperallergy. This is correct because ranitidine treats conditions related to excess stomach acid, and brompheniramine treats allergic symptoms.

4. **Evaluating the Reason:**
- The reason states that both drugs are antihistamines. While this is true, it is important to note that they belong to different classes of antihistamines (H2 and H1). Therefore, while both are antihistamines, their mechanisms and uses differ.

5. **Conclusion:**
- Since both the assertion and the reason are correct, and the reason provides a correct explanation for the assertion (as it highlights their classification as antihistamines), we conclude that the correct option is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.

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