Solution
The correct option is C Modified leaves only The flower is considered to be a modified shoot that is borne on the condensed thalamus. The thalamus shows four nodes with highly condensed internodes. These four nodes give rise to four whorls of the flower. So, the calyx, corolla, androecium and gynoecium are modified leaves that perform the function of protection, attraction, production of gametes respectively.
Hence, the correct answer is 'Modified leaves only'.
