Solution

The correct option is B Cytokinin
  • Cytokinins are plant growth hormones. They are amino derivatives. These hormones promote cell division in plants.
  • They also slow down the process of senescence. When the leaves are treated with cytokinins, these allow the mesophyll cells to produce more nutrients.
  • Hence, perishable vegetables are sprayed with a solution of cytokinin to keep them fresh for a longer time and increase their shelf life. They also prevent chlorophyll degradation.
Thus, the correct answer is option B.
