Solution
The correct option is A Dracaena
Dracaena is an unusual plant, in that the vascular bundles are surrounded by very prominent fibre bundles. In this sense, Dracaena is not anomalous. The stems undergo a specialized secondary growth, which manifests itself in the production of additional parenchymatous elements. Their later growth pattern is termed diffuse secondary growth, and consists mostly of a proliferation of ground parenchyma cells and additional vascular bundles near the periphery. Thus, option A is correct.
