Solution

The correct option is B Etiolation
Etiolation is a process which is seen in flowering plants that are grown in the partial or complete absence of light. It is characterized by slender yellowish stems, smaller yellowish leaves due to longer internodes, subterminal hook and chlorosis due to lack of chlorophyll. The growing tips are attracted towards the light and will elongate towards it.
Thus, the correct answer is option B.
