AIIMS 2018 Botany Cytokinins MCQ Question

Cytokinins are a class of plant hormones that promote cell division and growth, and include compounds such as kinetin, zeatin, and benzylaminopurine (BAP), all of which are known for their roles in various physiological processes in plants. Option A correctly lists these three compounds as they are all recognized as cytokinins. In contrast, options B and C incorrectly include gibberellins (GA₃), which are involved in different growth processes, while option D combines indole-3-acetic acid (IAA), a type of auxin, with zeatin and kinetin, which does not accurately represent the classification of cytokinins. Understanding the specific roles and classifications of these plant hormones is essential for grasping plant physiology.
