A : Na and Li are stored under kerosene.
R : Na and Li are soluble in kerosene.

Options

A. If both Assertion & Reason are true and the reason is the correct explanantion of the assertion, then mark (1).
B. If both Assertion & Reason are true and the reason is the correct explanantion of the assertion, then mark (2).
C. If Assertion is true statement but Reason is false. Them mark (3).
D. If both Assertion and reason are false statement, then mark (4).

Answer

To analyze the statements provided in the question, we need to evaluate both the assertion (A) and the reason (R) separately.

### Step 1: Evaluate the Assertion (A)
**Assertion (A): Na and Li are stored under kerosene.**
- Sodium (Na) is indeed stored under kerosene to prevent it from reacting with moisture and oxygen in the air.
- However, Lithium (Li) is not stored under kerosene; it is typically stored under paraffin wax or in a vacuum because it can react with kerosene.

**Conclusion for Assertion (A):** This statement is incorrect because while Na is stored under kerosene, Li is not.

### Step 2: Evaluate the Reason (R)
**Reason (R): Na and Li are soluble in kerosene.**
- Sodium does not dissolve in kerosene; rather, it is stored in kerosene to prevent reactions with air and moisture.
- Lithium also does not dissolve in kerosene. Both metals are not soluble in kerosene.

**Conclusion for Reason (R):** This statement is also incorrect because neither Na nor Li is soluble in kerosene.

### Final Conclusion
Both the assertion (A) and the reason (R) are false. Therefore, the correct answer is that both the assertion and the reason are false statements.
