The final step is Harvesting, and Sickles are usually used for harvesting.

Option B is the answer here because last step in crop production is crop harvesting

Harvesting is the last step in crop production
Harvesting is the final stage in the crop production cycle where the mature crops are collected from the fields. This process involves cutting, gathering, and storing the crop for further processing or distribution. Here are some key points to explain why harvesting is the last step in crop production:

Maturation of crops
- Harvesting is done when the crops have reached full maturity and are ready for consumption or further processing.
- It is essential to wait for the crops to reach their peak ripeness to ensure good quality and yield.

Timing is crucial
- Harvesting at the right time is crucial to prevent loss of yield and quality.
- Delayed harvesting can lead to over-ripening, shattering, or damage to the crops, resulting in lower yields.

End of the growth cycle
- Harvesting signifies the end of the growth cycle of the crop, marking the completion of the production process.
- Once the crops are harvested, the field is cleared for the next cycle of planting and cultivation.

Preservation and storage
- After harvesting, the crops need to be properly stored to prevent spoilage and maintain their quality.
- Proper storage conditions help in preserving the harvested crops for longer periods, ensuring a stable food supply.
In conclusion, harvesting is the final step in crop production as it involves collecting the mature crops after they have completed their growth cycle. This process is crucial for ensuring a successful yield and quality of the crops before they are further processed or distributed.
