C) Datura D) Citrus

Options

A. B, C, A, D
B. A, D, B, C
C. A, B, C, D
D. C, D, B, A

Answer

To arrange the given plants (Allium, Dolichos, Datura, Citrus) in ascending order based on the number of carpels, we need to analyze the number of carpels present in each plant:

1. **Identify the number of carpels in each plant:**
- **Dolichos (B)**: This plant belongs to the Fabaceae family and has a unicarpillary condition, which means it has **1 carpel**.
- **Datura (C)**: This plant is a member of the Solanaceae family and has a bicarpillary condition, meaning it has **2 carpels**.
- **Allium (A)**: This plant belongs to the Liliaceae family and exhibits a tricarpillary condition, which indicates it has **3 carpels**.
- **Citrus (D)**: This plant has a multicarpillary condition, meaning it has **many carpels** (typically more than 3).

2. **Arrange the plants based on the number of carpels:**
- Start with the plant with the least number of carpels:
- Dolichos (1 carpel)
- Datura (2 carpels)
- Allium (3 carpels)
- Citrus (many carpels)

3. **Final arrangement in ascending order:**
- **Dolichos (1 carpel)**
- **Datura (2 carpels)**
- **Allium (3 carpels)**
- **Citrus (many carpels)**

Thus, the correct ascending order based on the number of carpels is:
**B (Dolichos) < C (Datura) < A (Allium) < D (Citrus)**
