Solution

The correct option is B
Vernalization

There are plants for which flowering is either quantitatively or qualitatively dependent on exposure to low temperature. This phenomenon is termed vernalisation. Photoperiodism is the phenomenon of flowering in response to day length. Anthesis refers to the period during which flower is fully open and functional.
