The correct Answer is:
C
We will observe the protoxylem of the dicot stem and dicot root to distinguish between them. In dicot stem the protoxylem is present towards center (pith) and metaxylem is present towards the periphery of the organ . This type of xylem is known as endarch.
In root protoxylem is present towards periphery and metaxylem is present towards center that is called exarch.
