A : The chief component of biogas is `CH_(4)`.
R : Biogas plants are prepared on the foregin technology.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1)
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2).
C. If Assertion is true statement but Reaosn is false, then mark (3).
D. If both Assertion and Reason are false statements, then mark (4).

Answer

To analyze the statements provided in the question, we will break down the assertion (A) and the reason (R) step by step.

### Step 1: Analyze Assertion (A)
**Assertion (A): The chief component of biogas is CH₄.**

- Biogas is primarily composed of methane (CH₄), which is produced during the anaerobic digestion of organic matter, such as animal dung.
- The composition of biogas typically consists of about 65-70% methane, making it the chief component.
- Therefore, Assertion (A) is **True**.

### Step 2: Analyze Reason (R)
**Reason (R): Biogas plants are prepared on foreign technology.**

- Biogas plants utilize traditional methods for the anaerobic digestion of organic waste, which have been practiced for many years in various cultures.
- The technology for biogas production is not exclusively based on foreign technology; it has indigenous roots and has been adapted and improved over time.
- Therefore, Reason (R) is **False**.

### Step 3: Conclusion
- Since Assertion (A) is True and Reason (R) is False, the correct relationship between the two is that the assertion is true, but the reason is false.

### Final Answer
The correct option is that Assertion (A) is true and Reason (R) is false.
