Assertion: Lithium is most reducing element.
Reason: IP of lithium is minimum in the elements.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion
C. If Assertion is True but the Reason is False
D. If both Assertion & Reason are False

Explanation

To solve the question, we need to analyze the assertion and reason provided:

**Assertion:** Lithium is the most reducing element.
**Reason:** The ionization potential (IP) of lithium is minimum among the elements.

### Step-by-Step Solution:

1. **Understanding the Assertion:**
- The assertion states that lithium is the most reducing element. This is true because lithium, being a small alkali metal, has a high charge density and a strong tendency to lose its outermost electron. This makes it a strong reducing agent.

2. **Analyzing the Reason:**
- The reason given is that the ionization potential of lithium is the minimum among the elements. This statement is incorrect. In fact, lithium has the highest ionization potential among the alkali metals due to its small atomic size and the effective nuclear charge experienced by its outermost electron.

3. **Comparing Assertion and Reason:**
- Since the assertion is true (lithium is indeed a strong reducing agent), but the reason is false (the ionization potential of lithium is not minimum), we conclude that the assertion is true while the reason is false.

4. **Conclusion:**
- Therefore, the correct answer is that the assertion is true and the reason is false. This corresponds to option C.

### Final Answer:
- Assertion is true, Reason is false. Correct answer: Option C.
