Correct Answer:
Solution : The correct option is collateral.
A "collateral vascular bundle" is a vascular bundle in plant anatomy that has xylem and phloem tissues organised in the same radial location. This arrangement is prevalent in dicotyledonous plants, where the xylem is usually found in the centre of the stem or root and the phloem on the outside of the bundle. The arrangement of vascular tissues in a bundle has significant implications for water, nutrient and sugar transportation inside the plant.
