Assertion(A): Alcohols are dehydrated to hydrocarbons in the pressure of acidie zeolites.
Reason(R): Zeolites are porous catalysts.

Options

A. If both (A) and (R) are correct, and (R) is the correct explanation of (A)
B. If both (A) and (R) are correct, but (R) is the correct explanation of (A).
C. If (A) is correct, but (R) is incorrect.
D. If (A) is incorrect, but (R) is correct. S

Explanation

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

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "Alcohols are dehydrated to hydrocarbons in the presence of acidic zeolites."
- This is a true statement. Acidic zeolites, such as ZSM-5, are indeed used as catalysts to dehydrate alcohols, leading to the formation of hydrocarbons.

2. **Understanding the Reason (R)**:
- The reason states that "Zeolites are porous catalysts."
- This statement is also true. Zeolites have a porous structure that allows them to facilitate various catalytic reactions by providing a large surface area for reactants to interact.

3. **Analyzing the Relationship**:
- While both the assertion and the reason are true, we need to determine if the reason correctly explains the assertion.
- The assertion specifically mentions the dehydration of alcohols to hydrocarbons, while the reason describes a property of zeolites (their porosity).
- The porosity of zeolites does contribute to their catalytic activity, but it does not directly explain why they are effective in dehydrating alcohols to hydrocarbons.

4. **Conclusion**:
- Since both statements are correct, but the reason does not provide a correct explanation for the assertion, the answer is that the assertion is correct, the reason is correct, but the reason is not the correct explanation of the assertion.

### Final Answer:
The correct option is **B**: Assertion is correct, reason is correct, but reason is not the correct explanation of assertion.
