Option 1 -> Incorrect because Oestrogen is an animal hormone, not a plant hormone.
Option 2 -> Correct as Auxin, Gibberellins, and Abscisic acid are all plant hormones.
Option 3 -> Incorrect because Oestrogen is an animal hormone involved in reproduction, not a plant hormone.
Option 4 -> Incorrect because it excludes Auxin (a key plant hormone) and includes Oestrogen (an animal hormone).
Hence, Option 2: (A), (B) and (D) only -> Auxin regulates cell elongation and growth, Gibberellins promote stem elongation and germination, and Abscisic acid controls stress responses and dormancy - all are true plant hormones. Oestrogen is an animal steroid hormone and should be excluded -> correct
