Solution
The correct option is B Endarch
The cells of vascular bundles develop from the procambial cells. In endarch condition, the protoxylem develops from the innermost procambial cells and progresses outwards. Hence metaxylem appear towards outside and protoxylem appears towards innerside. During root-stem transition, the arrangements of xylem and phloem changes which leads to the endarch condition in stem which was initially exarch in root. So, the correct answer is 'Endarch.'
