B. Phytoalexins
C. Triazine
D. Hormones

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks why green potatoes are toxic. We need to identify the compound responsible for their toxicity.

2. **Analyzing the Options**: The options provided are:
- A) Solanin
- B) Phytoallergens
- C) Triazine
- D) Hormones

3. **Evaluating Option A - Solanin**:
- Solanin is a glycoalkaloid poison found in the nightshade family (Solanaceae), which includes potatoes and tomatoes.
- When potato tubers are exposed to light, they turn green and produce more solanin, making them toxic.

4. **Evaluating Option B - Phytoallergens**:
- Phytoallergens are low molecular weight antimicrobial compounds. They are not responsible for the toxicity of green potatoes, making this option incorrect.

5. **Evaluating Option C - Triazine**:
- Triazines are selective herbicides used to control various types of grass. They do not relate to the toxicity of potatoes, so this option is also incorrect.

6. **Evaluating Option D - Hormones**:
- Hormones are chemical messengers in plants but are not responsible for the toxicity of green potatoes. Therefore, this option is incorrect as well.

7. **Conclusion**: After evaluating all options, the correct answer is **A) Solanin**, as it is the compound responsible for the toxicity in green potatoes.

**Final Answer**: Green potatoes are toxic because of **solanin**.
