Sprouting of potato can be prevented in storage by

Options

A. Maleic hydrazide
B. Gibberellins
C. Indole acetic acid
D. Cytokinins.

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks how to prevent the sprouting of potatoes during storage. This indicates that we are looking for a method or substance that inhibits sprouting.

2. **Identifying the Options**: The options provided are:
- Maleic hydrazide
- Gibberellins
- Indole acetic acid
- Cytokinins

3. **Analyzing Plant Growth Regulators**: All the options listed are plant growth regulators (phytohormones). It's important to understand the role of each in plant growth:
- Gibberellins promote growth and cell division.
- Indole acetic acid (IAA) is involved in cell elongation and division.
- Cytokinins promote cell division and growth.

4. **Determining the Effect on Sprouting**: Since sprouting involves cell division and growth, any substance that promotes these processes would not be suitable for preventing sprouting. Therefore, gibberellins, indole acetic acid, and cytokinins can be eliminated as they promote sprouting.

5. **Identifying the Correct Answer**: The only option left is maleic hydrazide. This substance is known to inhibit cell division and growth, making it effective in preventing sprouting in potatoes during storage.

6. **Conclusion**: The correct answer to the question is maleic hydrazide, as it inhibits the processes that lead to sprouting.

**Final Answer**: Sprouting of potato can be prevented in storage by maleic hydrazide.
