Correct Answer: Option(a)
Solution: Etiolation is a process which is seen in flowering plants that are grown in partial or complete absence of light. It is characterized by slender yellowish stems, smaller yellowish leaves due to longer internodes, suberminal hook and chlorosis due to lack of chlorophyll. The growing tips are attracted towards light and will elongate towards it.
