Solution

The correct option is B Etiolation
Etiolation is a process in flowering plants grown in partial or complete absence of light. It is characterized by long, weak stems, smaller, sparser leaves due to longer internodes and a pale yellow colour called as chlorosis. It increases the likelihood that a plant will reach a light source, often from under leaf litter, or shade from competing plants. The growing tips are strongly attracted to light and will elongate towards it.
