Assertion :- Stilt root is a example of supporting root.
Reason :- Stilt root is modified tap root.

Options

A. If both Assertion & Reason are True & Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True & the 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.

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Assertion**: The assertion states that "Stilt root is an example of supporting root." This is true because stilt roots provide additional support to the plant, helping it to stand upright, especially in plants like maize and sugarcane.

2. **Understanding the Reason**: The reason states that "Stilt root is a modified tap root." This is false. Stilt roots are not modified tap roots; they are actually modified adventitious roots.

3. **Differentiating Root Types**:
- **Tap Roots**: These are the primary roots that develop from the radical of the seed. They grow deep into the soil.
- **Adventitious Roots**: These roots develop from parts of the plant other than the radical, such as stems or leaves. Stilt roots fall into this category.

4. **Conclusion**: Since the assertion is true (stilt roots do provide support) and the reason is false (stilt roots are not modified tap roots), the correct option is that the assertion is true, but the reason is false.

**Final Answer**: Assertion is true; Reason is false.
