Answer & Solution
Correct answer: D. the promotion of flowering by a prior cold treatment
Vernalisation is the requirement (or promotion) of flowering by a period of low temperature, classically a winter chill in biennials like cabbage or in winter wheat. Internally, cold turns off the FLC repressor of flowering. Distinct from germination, stomatal movement and wind response.
