Explanation
- The question tests knowledge of plant hormone functions.
- Cytokinins → promote cell division.
- Auxins → promote cell elongation/phototropism; Gibberellins → promote stem elongation/seed germination; Abscisic acid → inhibits growth/promotes wilting.
- The NCERT exercise (Chapter 6, Q.1) directly identifies Cytokinin as a plant hormone, and the chapter text links it to cell division.
