Plant hormone controlling fruit ripening is

Options

A. IAA
B. GA
C. Ethylene
D. Kinetin

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks which plant hormone is responsible for controlling fruit ripening.

2. **Review the Options**: The options provided are:
- IAA (Indole-3-acetic acid)
- GA (Gibberellic acid)
- Ethylene
- Kinetin

3. **Analyze Each Option**:
- **Option 1: IAA (Indole-3-acetic acid)**: This is a type of auxin, which is primarily involved in regulating growth and developmental processes, but not specifically in fruit ripening. Therefore, this option is incorrect.

- **Option 2: GA (Gibberellic acid)**: Gibberellic acid is known for its role in promoting cell division and elongation. It does not play a significant role in fruit ripening, making this option incorrect as well.

- **Option 3: Ethylene**: Ethylene is a gaseous plant hormone that is directly involved in the processes of growth, development, and particularly in fruit ripening. This option is correct as it specifically controls fruit ripening.

- **Option 4: Kinetin**: Kinetin is a type of cytokinin that promotes cell division but does not have a direct role in fruit ripening. Thus, this option is also incorrect.

4. **Conclusion**: After analyzing all the options, the correct answer is **Ethylene**, as it is the plant hormone that controls fruit ripening.

**Final Answer**: Ethylene
