Solution
The correct option is B Vitis
At the interface between two sieve tube members in angiosperms are sieve plates which are pores in the plant cell walls that facilitate transport of materials. Each sieve tube element is normally associated with one or more nucleated companion cells, to which they are connected by plasmodesmata. Young sieve plates in Vitis have paired callose platelets in pore sites, each of which is penetrated by a single plasmodesma. They have compound sieve plates. So, the correct answer is option B.
