Exstipulated leaves are found in
I) Fabaceae II) Potato family
III) Lily family

Options

A. I only
B. II only
C. III only
D. II and III

Answer

To determine which families have exstipulated leaves, we need to understand what exstipulated leaves are and identify the characteristics of the given plant families.

### Step-by-Step Solution:

1. **Define Exstipulated Leaves**:
- Exstipulated leaves are leaves that do not have stipules. Stipules are small leaf-like structures that can be found at the base of the leaf stalk (petiole).

2. **Identify the Families**:
- The question provides three options:
- I) Fabaceae (Legume family)
- II) Potato family (Solanaceae)
- III) Lily family (Liliaceae)

3. **Analyze Each Family**:
- **Fabaceae**: Members of this family typically have stipules. Examples include pea, bean, and gram. Therefore, Fabaceae does **not** have exstipulated leaves.
- **Potato Family (Solanaceae)**: Members of this family, such as potato and tomato, generally have exstipulated leaves. Thus, this family does have exstipulated leaves.
- **Lily Family (Liliaceae)**: Members of this family, such as tulip and aloe, also typically have exstipulated leaves. Therefore, this family also has exstipulated leaves.

4. **Conclusion**:
- Based on the analysis, exstipulated leaves are found in:
- II) Potato family
- III) Lily family
- The correct answer is that exstipulated leaves are found in the Potato family and Lily family.

### Final Answer:
Exstipulated leaves are found in:
- II) Potato family
- III) Lily family
