Answer 1

The correct option is D Collateral.

A vascular bundle in which a strand of phloem is present external to the strand of xylem on the same radius side by side is known as collateral bundle.

(a) Closed collateral bundle: In this type cambium is absent in between xylem and phloem.

(b) Open collateral bundle: An open collateral vascular bundle has cambium called fascicular cambium between xylem and phloem.

So, the correct answer is 'Collateral'.
