Correct answer
A. vernalization
Step-by-step solution
Vernalization is chilling or cold treatment of the young plants or seeds to induce flowering. It is a process of shortening of the juvenile or vegetative phase and fastening the flowering by a process of cold treatment. It was first reported by a Russion worker, Lysenko (1928) while working on cold requiring biennial plants.
