Assertion: Alcohol is called a stimulant.
Reason: Alcohol is immediately oxidised to produce large amount of energy which increases the activities of CNS.

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 "Alcohol is called a stimulant." To analyze this, we need to understand what a stimulant is. Stimulants are substances that increase the activity of the central nervous system (CNS), leading to increased alertness, attention, and energy.

2. **Evaluating the Reason**: The reason given is that "Alcohol is immediately oxidized to produce a large amount of energy which increases the activities of the CNS." Here, we need to assess whether alcohol indeed increases CNS activity and if it is oxidized to produce energy.

3. **Analyzing Alcohol's Effects**: In reality, alcohol is classified as a depressant rather than a stimulant. It slows down brain activity and depresses the functions of the CNS. This contradicts the assertion that alcohol is a stimulant.

4. **Examining the Oxidation of Alcohol**: While it is true that alcohol is metabolized (oxidized) in the body, the energy produced does not lead to an increase in CNS activity. Instead, the effects of alcohol lead to decreased alertness and slower cognitive functions.

5. **Conclusion**: Since the assertion that "Alcohol is called a stimulant" is false, and the reason that "Alcohol is immediately oxidized to produce large amounts of energy which increases the activities of the CNS" is also false, we conclude that both statements are incorrect.

**Final Answer**: Both the assertion and the reason are false.
