B. Groundnut
C. Pea
D. Castor

Answer

To solve the question of finding the odd one out with respect to non-endospermic seeds, we can follow these steps:

### Step 1: Understand the Concept of Endospermic and Non-Endospermic Seeds
- **Endospermic Seeds**: These seeds contain endosperm, a nutritive tissue that provides nourishment to the developing embryo. Examples include seeds of monocots and some dicots.
- **Non-Endospermic Seeds**: These seeds do not have endosperm at maturity as it is completely utilized during the development of the seed. Examples include gram, pea, and groundnut.

### Step 2: Analyze the Given Options
The options provided are:
1. Gram
2. Groundnut
3. Pea
4. Castor

### Step 3: Identify the Type of Each Seed
- **Gram (Cicer arietinum)**: Non-endospermic seed.
- **Groundnut (Arachis hypogaea)**: Non-endospermic seed.
- **Pea (Pisum sativum)**: Non-endospermic seed.
- **Castor (Ricinus communis)**: Endospermic seed.

### Step 4: Determine the Odd One Out
From the analysis:
- Gram, Groundnut, and Pea are all non-endospermic seeds.
- Castor is the only seed that is endospermic.

### Conclusion
The odd one out with respect to non-endospermic seeds is **Castor**.
