Solution
The correct option is B Amphivasal
When xylem surrounds the phloem tissue from all sides the vascular bundle is called as an amphivasal vascular bundle or leptocentric type. Such bundles are seen in monocot plants, like Dracaena after secondary growth. When phloem surrounds the xylem tissue entirely, the vascular bundle is called as amphicribal vascular bundle or hadrocentric type. Such vascular bundles are seen in pteridophytes, like Lycopodium, SelaginellaSo, the correct answer is 'Amphivasal'
