By identifying the shape of the potato, select the option that represents the causative agent for this condition

Options

A. Virus
B. Virion
C. Viroid
D. Prion

Answer

To solve the question regarding the causative agent represented by the shape of the potato, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks us to identify the causative agent based on the shape of the potato. We need to analyze the options provided to determine which one corresponds to the observed characteristics of the potato.

2. **Analyze the Options**:
- **Virus**: Viruses typically have a genetic material core (nucleic acid) surrounded by a protein coat. The potato does not exhibit this structure, indicating that a virus is not the correct option.

- **Viron**: A viron is an infectious form of a virus. Similar to viruses, virons also have a protein coat and do not match the shape of the potato. Therefore, this option is also incorrect.

- **Viroid**: Viroids are smaller than viruses and lack a protein coat. They consist of naked genetic material. Since the potato shows no covering and is affected by a causative agent that alters its structure, viroids are a strong candidate. The viroid is known to cause diseases in plants, including potatoes, leading to changes in their shape.

- **Prion**: Prions are infectious agents that cause diseases primarily in the brain. They are not associated with the shape or structure of potatoes, making this option incorrect.

3. **Select the Correct Option**: Based on the analysis, the option that best represents the causative agent for the condition affecting the potato is **Viroid**.

### Final Answer:
The correct option representing the causative agent for the condition affecting the potato is **Viroid**.
