The correct option is C Companion cell
Gymnosperms are primitive than the angiosperms. Sieve tube member is associated with one or more specialized parenchyma cells called as companion cells which are seen only in angiosperms. Both, sieve tube member and companion cell are derived from the same meristematic cell. Companion cell is nucleated. These cells provide energy for food conduction.Thus, the correct answer is option C.
