Which of the following sequence of pre-planting operation is correct?

The correct sequence of pre-planting operations is bush clearing, burning and stumping, farm layout. This is because the first operation is usually to clear the farm of any bushes or trees that might hinder planting activities. After the clearing, the next operation is to burn any remaining vegetation and stumps to provide ashes and nutrients for the soil. The farm layout is then marked out, indicating the rows and planting spots, to ensure proper spacing and arrangement of crops. Therefore, option D, which starts with bush clearing, followed by burning, stumping and farm layout is the correct sequence of pre-planting operations.
