Assertion : Lightning is caused by the accumulation of charges in clouds.
Reason : The process of meeting of negative and positive charges to release huge amount of energy is called electric discharge.

Options

A. If both assertion and reason are true and reason is the 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 assertion is false but reason is true.

Answer

To analyze the assertion and reason provided in the question, we will break down each component step by step.

### Step 1: Understanding the Assertion
The assertion states that "Lightning is caused by the accumulation of charges in clouds."
- **Explanation**: During thunderstorms, clouds become charged due to various processes, such as collisions between water droplets and ice particles. This charge separation leads to an accumulation of negative charges at the bottom of the cloud and positive charges at the top.

### Step 2: Understanding the Reason
The reason states that "The process of meeting of negative and positive charges to release a huge amount of energy is called electric discharge."
- **Explanation**: Electric discharge occurs when there is a sudden flow of electricity between two charged regions. In the case of lightning, it is the discharge of electricity between the negatively charged cloud and the positively charged ground or another cloud.

### Step 3: Evaluating the Relationship
Now we need to evaluate if the reason correctly explains the assertion.
- **Analysis**: While both statements are true, the reason does not specifically define lightning. Instead, it describes electric discharge in general. Lightning is a specific type of electric discharge that occurs in the atmosphere.

### Conclusion
- **Final Answer**: Both the assertion and reason are true, but the reason does not correctly explain the assertion. Therefore, the answer is option 2: "Both assertion and reason are true, but reason is not the correct explanation of assertion."
