Statement-I : Law of conservation of mass hold good for nuclear reaction.
Because
Statement-II : Law states that mass can be neither created nor destroyed in a chemical reaction.

Options

A. Statement-I is true, Statement-II is true , Statement-II is correct explanation for Statement-I
B. Statement-I is true, Statement-II is true , Statement-II is `NOT` a correct explanation for statement-I
C. Statement-I is true, Statement-II is false
D. Statement-I is false, Statement-II is true

Answer

To analyze the statements and determine their validity, we can break down the reasoning step by step.

### Step 1: Understand Statement-I
**Statement-I**: "Law of conservation of mass holds good for nuclear reaction."

- The law of conservation of mass states that mass cannot be created or destroyed in a closed system. However, in nuclear reactions, this law does not strictly hold because some mass is converted into energy according to Einstein's equation \(E=mc^2\). Therefore, Statement-I is **false**.

### Step 2: Understand Statement-II
**Statement-II**: "Law states that mass can be neither created nor destroyed in a chemical reaction."

- This statement is true. In chemical reactions, the total mass of the reactants is equal to the total mass of the products. Therefore, Statement-II is **true**.

### Step 3: Analyze the Relationship Between the Statements
- Statement-I claims that the law of conservation of mass applies to nuclear reactions, which we have established is false.
- Statement-II correctly describes the law of conservation of mass in the context of chemical reactions but does not provide a valid explanation for Statement-I since Statement-I is false.

### Conclusion
- **Statement-I** is **false**.
- **Statement-II** is **true**.
- Therefore, the correct conclusion is that Statement-I is not supported by Statement-II.

### Final Answer
- Statement-I is false, and Statement-II is true.
