The correct answer is d.

Zero tillage in agriculture has the following advantages:

Sowing of what is possible without burning the residue of previous crop: Zero tillage allows farmers to sow crops without the need to burn the residue of the previous crop, which can improve soil fertility and reduce greenhouse gas emissions.

Without the need for a nursery of rice saplings, direct planting of paddy seeds in the wet soil is possible: Zero tillage eliminates the need for nursery-grown rice saplings, allowing farmers to directly plant paddy seeds in wet soil. This can save time and labor.

Carbon sequestration in the soil is possible: Zero tillage can help to sequester carbon in the soil, which can help to mitigate climate change. When farmers do not disturb the soil, the organic matter in the soil is not oxidized and is instead stored in the soil.
