Solution

The correct option is B Low temperature
Vernalization is the process by which plant can be induced to flower by exposing it to the prolonged cold of winter. The term was coined by Lysenko in 1928. He stated that certain plants can be made to flower by providing low temperature treatment to young plants or moistened seeds. Other terms like jarovization, springification were also coined for the same phenomenon.
Thus, the correct answer is option B.
