  • A. auxin
  • B. gibberellins
  • C. abscisin ✓
  • D. cytokinins

 

The answer to the question is: C. abscisin

The farmer who wants to keep seeds for three years before planting and prevent them from sprouting would use abscisic acid (ABA). ABA is a plant hormone that plays a crucial role in seed dormancy and germination. It inhibits seed germination and promotes seed dormancy, which would be beneficial for the farmer’s purpose of preserving the seeds for an extended period.

When seeds are exposed to ABA, it suppresses the expression of genes that are involved in promoting germination. This hormone also regulates the synthesis of proteins and lipids that are essential for maintaining seed dormancy. By using ABA, the farmer can effectively prevent the seeds from sprouting during the storage period.
