B. Rice
C. Coconut
D. Wheat

Answer

To solve the question regarding which one is odd regarding endospermic seeds, we will follow these steps:

### Step 1: Understand the Types of Seeds
- There are two main types of seeds: endospermic (or albuminous) seeds and non-endospermic (or exalbuminous) seeds.
- Endospermic seeds contain a food reserve in the form of endosperm, which is the tissue produced inside the seeds after fertilization.

### Step 2: Identify Examples of Endospermic Seeds
- Common examples of endospermic seeds include rice, wheat, and coconut.
- These seeds have a significant amount of endosperm that serves as a food source for the developing plant.

### Step 3: Identify Examples of Non-Endospermic Seeds
- Non-endospermic seeds do not contain endosperm. An example of a non-endospermic seed is the orchid.
- In these seeds, the food reserves are stored in the cotyledons instead of the endosperm.

### Step 4: Analyze the Options Given
- The options provided are: orchid, rice, coconut, and wheat.
- Rice, coconut, and wheat are all examples of endospermic seeds, while orchid is a non-endospermic seed.

### Step 5: Determine the Odd One Out
- Since the question asks for the odd one regarding endospermic seeds, we identify that orchid is the only seed listed that does not have endosperm.
- Therefore, the odd one out is orchid.

### Final Answer
- The answer is **orchid** (option A).
