The process of induction of flowering in plants, by exposing seeds at low temperature for prolonged periods is called Vernalisation. It is an aerobic, temperature dependent phenomena, prevents precocious reproductive development. It does not depend on light.

So, the correct answer to the question is ‘vernalisation is not a light dependent phenomena’.

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. Many plants grown in temperate climates require vernalization and must experience a period of low winter temperature to initiate or accelerate the flowering process. This ensures that reproductive development and seed production occurs in spring and summer, rather than in autumn.

 Vernalization is the process of induction of flower by prolonged exposure to cold temperature. It is an adaptation shown by plants which are exposed to harsh winter followed by relatively short growing seasons. Vernalization is practiced artificially too.

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. 

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.
