Assertion: During the process of respiration, oxygen is utilised and carbon dioxide. water and energy is released as products.
Reason: The combustion reaction does not require oxygen.

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 but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

To analyze the given assertion and reason, let's break it down step by step:

### Step 1: Understand the Assertion
The assertion states: "During the process of respiration, oxygen is utilized and carbon dioxide, water, and energy are released as products."

- **Explanation**: In cellular respiration, glucose (C6H12O6) is broken down in the presence of oxygen (O2) to produce carbon dioxide (CO2), water (H2O), and energy (in the form of ATP). This process is essential for the survival of aerobic organisms.

### Step 2: Validate the Assertion
- The assertion is true because it accurately describes the process of aerobic respiration. The general equation for aerobic respiration is:
\[ \text{C}_6\text{H}_{12}\text{O}_6 + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O} + \text{Energy (ATP)} \]

### Step 3: Understand the Reason
The reason states: "The combustion reaction does not require oxygen."

- **Explanation**: Combustion typically refers to a chemical reaction where a substance (usually a hydrocarbon) reacts with oxygen to produce heat, carbon dioxide, and water. The statement in the reason is incorrect because combustion reactions generally require oxygen to occur.

### Step 4: Validate the Reason
- The reason is false because combustion reactions do require oxygen. Without oxygen, combustion cannot take place. Therefore, the reason does not support the assertion.

### Step 5: Conclusion
- Since the assertion is true and the reason is false, we conclude that the assertion stands alone without the support of the reason.

### Final Answer
The correct option is C: The assertion is true, but the reason is false.
