Model Answer
C — Abscisic acid
Abscisic acid is a plant growth inhibitor hormone whose effects include wilting of leaves.
Explanation
The textbook explicitly states: "Abscisic acid is one example of a hormone which inhibits growth. Its effects include wilting of leaves." Auxin and gibberellin promote stem growth; cytokinin promotes cell division — none inhibit growth or cause wilting.
