Identify the correct pair of plants with odd number of leaflets in compound leaf

Options

A. Hardwickia, Gynandropsis
B. Citrus, Aegle marmelos
C. Marsilea, Gynandropsis
D. Aegle marmelos, Hardwickia

Answer

To solve the question of identifying the correct pair of plants with an odd number of leaflets in a compound leaf, we can follow these steps:

### Step 1: Understand the Concept of Leaflets
- A compound leaf is made up of multiple leaflets. The number of leaflets can be odd (1, 3, 5, 7, etc.) or even (2, 4, 6, etc.).

**Hint**: Remember that odd numbers are those that cannot be divided by 2 evenly.

### Step 2: Analyze Each Plant Option
- We need to evaluate the given plants to see how many leaflets each has.

1. **Hardwickia**:
- Contains 2 leaflets (even).
- **Conclusion**: Incorrect for our requirement.

2. **Gynandropsis**:
- Contains 3 to 5 leaflets (odd).
- **Conclusion**: Correct, but we need to find a pair.

3. **Citrus**:
- Contains 3 leaflets (odd).
- **Conclusion**: Correct, and can be paired with another plant.

4. **Agar Marmelos**:
- Contains 3 leaflets (odd).
- **Conclusion**: Correct, and can be paired with Citrus.

5. **Marsilia**:
- Contains 4 leaflets (even).
- **Conclusion**: Incorrect for our requirement.

### Step 3: Identify the Correct Pair
- From the analysis:
- **Citrus** (3 leaflets) and **Agar Marmelos** (3 leaflets) both have an odd number of leaflets.

**Final Conclusion**: The correct pair of plants with an odd number of leaflets in a compound leaf is **Citrus and Agar Marmelos**.

### Summary of Findings
- Hardwickia: 2 leaflets (even) - Incorrect
- Gynandropsis: 3-5 leaflets (odd) - Correct but needs a pair
- Citrus: 3 leaflets (odd) - Correct
- Agar Marmelos: 3 leaflets (odd) - Correct
- Marsilia: 4 leaflets (even) - Incorrect

### Final Answer
The correct pair of plants with an odd number of leaflets in a compound leaf is **Citrus and Agar Marmelos**.
