The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Climacteric Fruits**: Climacteric fruits are those that continue to ripen after being harvested. This ripening process is characterized by a significant increase in respiration and the production of ethylene, a plant hormone that promotes ripening. 2. **Identifying Characteristics**: The key characteristics of climacteric fruits include: - A high respiration rate during ripening. - Increased production of ethylene gas. - Changes in taste and color as the fruit ripens. 3. **Evaluating the Options**: - **Option 1: Autochory** - This refers to self-dispersal of seeds and is not related to the ripening process of fruits. Therefore, this option is incorrect. - **Option 2: Persistent flower part** - This does not relate to climacteric fruits and is also incorrect. - **Option 3: High respiration rate and ethylene at ripening** - This accurately describes the characteristics of climacteric fruits. Hence, this option is correct. - **Option 4: Both 2nd and 3rd** - Since option 2 is incorrect, this option is also incorrect. 4. **Conclusion**: The correct answer is **Option 3**, which states that climacteric fruits show a high respiration rate and increased ethylene production during ripening. ---
