In many plants, the temperature has a profound effect on flowering. Some plants do not flower under the inductive photoperiod conditions but flower when a cold temperature treatment is given to them. This acquisition or acceleration of the ability to flower by a chilling treatment is said to be vernalization. It is the method of inducing early flowering in plants by pretreatments of their seeds at a very low temperature. Thus option B is the correct answer. 

Vernalization (from Latin vernus, "of the spring") is the induction of a plant's flowering process by exposure to the prolonged cold of winter. After vernalization, plants have acquired the ability to flower. Through this process the quality of the crops can be improved, it helps to keep away the plants from the fungal disease and also helps to reduce the cost of the production.
So, the correct answer is option D.

During spring season the cool-season crops plants have enough time to reach maturity before the weather turns warm. Vernalization if the process of cooling the seed to germinate and induce flowering process.

Vernalization if the process of artificial induction of plant's flowering process which is discovered by Gassner and flowering time also changed by external factors.

The acquisition or acceleration of the ability to flower by a chilling treatment is said to be vernalization. It is the method of inducing early flowering in plants by pretreatments of their seeds at a very low temperature. Low-temperature effects may be obtained at any stage of plant development. The most effective temperature for vernalization is between 0 to 5 degree C. The duration of cold treatment for effective vernalization varies from four days to eight weeks. Thus option C is the correct answer. 

Vernalization is the acquisition of a plant's ability to flower in the spring by exposure to the prolonged cold of winter, or by an artificial equivalent. It can also refer to herbal plants requiring a cold dormancy to produce new shoots and leaves. The stimulus of vernalization is known as vernalin. The stimulus of vernalization that induce flowering could be a particular gibberellin or a mixture of gibberellins.

• Vernalization is a method in which the seeds or the plants are exposed to certain treatments in order to initiate the process of flowering. 
• Generally, the plants are exposed to cold treatment, which induces the plants to produce flowers. 
• This term was introduced by T. D. Lysenko in the year 1920.
• Thus, the correct answer is option B.
