Solution
The correct option is B Amphivasal
When the phloem surrounds the xylem
tissue completely. The vascular bundle is known as an amphicribal vascular
bundle or an androcentric type. Such vascular bundles are possible in
pteridophytes.
In the Concentric bundle, xylem either
encircles or is encircled by the phloem. Accordingly, the Amphivasal bundle is
a vascular bundle in which xylem encircles the central strand of phloem and it
is called amphivasal bundle or leptocentric bundle.
In the conjoint, these vascular bundles
xylem and phloem are present on the same radii.
A collateral arrangement is having xylem
and phloem next to each other.
So, the correct answer is 'Concentric
leptocentric/amphivasal.
The correct option is B.
