• B. Hormones regulating secondary growth.
• C. Growth regulators synthesized by plants and influencing physiological processes.
• D. Hormones regulating flowering.

Answer 1

Answer: (C)

Growth regulators synthesized by plants and influencing physiological processes.

• Phytohormones are growth regulators synthesized by plants and influencing physiological processes.
• They are produced by plants and control or regulate germination, growth, metabolism, or other physiological activities. For examples, Auxins, gibberellins, cytokinins, ethylene, and abscisic acid.
• Hence Phytohormones are growth regulators synthesized by plants and influencing physiological processes.
• So, 9*the correct answer is 'Growth regulators synthesized by plants and influencing physiological processes'.
