The correct Answer is:
To answer the question "A seed which is unable to germinate in the presence of light is," we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Types of Seeds**: - Seeds can be classified based on their germination requirements in relation to light. - There are two main categories: - **Positive Photoblastic Seeds**: These seeds require light to germinate. - **Negative Photoblastic Seeds**: These seeds do not germinate in the presence of light. 2. **Identify Negative Photoblastic Seeds**: - Negative photoblastic seeds are those that are unable to germinate when exposed to light. - Examples of negative photoblastic seeds include onion and lily. 3. **Analyze the Options**: - The options given are: - A) Viscum - B) Onion - C) Green - D) Maize - Among these, we need to identify which one is a negative photoblastic seed. 4. **Select the Correct Answer**: - From the analysis, we know that onion is a negative photoblastic seed, meaning it does not germinate in the presence of light. - The other options (Viscum, Green, Maize) are positive photoblastic seeds, which means they can germinate in the presence of light. 5. **Conclusion**: - Therefore, the answer to the question is **B) Onion**. ### Final Answer: The seed which is unable to germinate in the presence of light is **Onion**.
