B. Mutated
C. Embolised
D. Etiolated

Answer

To solve the question regarding the description of the white-colored tomato seedlings that were kept in a dark room, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Scenario**: The question describes normal tomato seedlings that were kept in a dark room and subsequently turned white, resembling albinos. This indicates a change in their pigmentation.

2. **Identify the Key Terms**: The options provided are:
- Defoliated
- Mutated
- Embolished
- Etiolated

3. **Define Each Term**:
- **Defoliated**: This refers to the loss of leaves from a plant, often due to external factors or chemical treatment.
- **Mutated**: This term pertains to changes in the genetic material (DNA) of an organism, which can lead to various traits or diseases.
- **Embolished**: This term is not commonly used in plant biology and generally refers to blockage in blood vessels in animals.
- **Etiolated**: This term describes the condition of plants that grow in insufficient light, characterized by elongated stems and pale leaves due to the lack of chlorophyll.

4. **Analyze the Condition of the Seedlings**: The white color of the seedlings suggests that they lack chlorophyll, which is typically produced in the presence of light. The absence of light leads to etiolated growth, where the plants stretch towards the light source and lose their green pigmentation.

5. **Select the Correct Term**: Based on the definitions and the condition of the seedlings, the correct term to describe the white-colored tomato seedlings is **etiolated**.

### Final Answer:
The correct term to describe the white-colored tomato seedlings is **etiolated**.
