Tillage is an agriculture land preparation through mechanical agitation which includes digging, stirring and overturning.

Zero tillage is the process where the crop seed will be sown through drillers without prior land preparation and disturbing the soil where previous crop stubbles are present. Zero tillage not only reduce the cost of cultivation it also reduces the soil erosion, crop duration and irrigation requirement and weed effect which is better than tillage. Zero Tillage (ZT) also called No Tillage or Nil Tillage.
Direct Seeded Rice Zero-Tillage DSR is an alternative crop establishment method for rice where seeds are sown directly without raising them in a nursery, and can be done in zero-tillage conditions.
If crops are not burnt and land is prepared through mechanical agitation, carbon sequestration remains possible.

Hence option 4th is correct.
