In the dicot root the vascular cambium originates from :
(1) Intrafascicular and interfascicular tissue in a ring
(2) Tissue located below the phloem bundles and a portion of pericycle tissue above protoxylem.
(3) Cortical region
(4) Parenchyma between endodermis and pericycle

The correct option is (2) Tissue located below the phloem bundles and a portion of pericycle tissue above protoxylem.

This is because – Vascular cambium is a secondary meristematic tissue, in dicot roots. It is originated from tissue located below the phloem bundles and a portion of pericycle tissue above the protoxylem.
