Vernalization is the process of inducing flowering to a plant by exposing the plant to cold of winter or through artificial processes. The process of Vernalization converts a biennial into an annual and spring variety into a winter variety and an annual into a perennial.

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 C is the correct answer. 

Vernalization is the induction of a plant's flowering process by exposure to the prolonged cold of winter. Therefore, it is classified as a temperature dependent pathway.

Vernalization promotes early flowering in plants that would otherwise require a longer vegetative period, effectively shortening the time spent in the vegetative phase.

When gibberellins were applied to certain cold-requiring plants, they flowered without low-temperature treatment. Thus it is conceivable that gibberellins could induce certain changes within the plant which in turn lead to flowering. Thus option B is the correct answer. 

Carrots are biennial plants that require a period of cold (vernalization) during their first year of growth to trigger flowering in the second year.

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.

Gustav Gassner is credited with the discovery of the phenomenon of vernalization in 1918, observing that cold treatment could induce flowering.

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.
