Which option correctly matches a plant hormone with its function?
Answer and explanation
Correct answer: Cytokinin and cell division
The governing concept is that plant hormones regulate plant growth and development in characteristic ways. Cytokinin promotes cell division, particularly in actively growing tissues, so option B gives a correct hormone-function pair. Abscisic acid generally inhibits growth and mediates stress responses; gibberellin and auxin are plant hormones but do not regulate blood sugar or heartbeat. Those distractors incorrectly assign animal functions to plant hormones.
