Answer

To arrange the given taxa (Nymphaea, Solanum, Mango, and Cucumber) in increasing order based on the number of carpels present in their ovaries, we will analyze each taxon step by step.

### Step 1: Identify the number of carpels in each taxon
- **Nymphaea**: This plant has more than 3 carpels in its ovary.
- **Solanum**: This plant has a bilocular ovary, which means it has 2 carpels.
- **Mango**: This plant has a single carpel (monocarpellary).
- **Cucumber**: This plant has 3 carpels in its ovary.

### Step 2: List the number of carpels for each taxon
- Nymphaea: > 3 carpels
- Solanum: 2 carpels
- Mango: 1 carpel
- Cucumber: 3 carpels

### Step 3: Arrange the taxa in increasing order based on the number of carpels
1. **Mango** (1 carpel)
2. **Solanum** (2 carpels)
3. **Cucumber** (3 carpels)
4. **Nymphaea** (> 3 carpels)

### Final Arrangement
Thus, the increasing order based on the number of carpels present in their ovaries is:
**Mango < Solanum < Cucumber < Nymphaea**
