Explanation:
Detailed explanation-1: -The first formed primary xylem is called protoxylem and the later formed primary xylem is called metaxylem. In stems, the protoxylem lies towards the centre (pith) and the metaxylem lies towards the peripheryof the organ. This type of primary xylem is called endarch.
Detailed explanation-2: –In exarch condition, the protoxylem (the first-formed xylem) lies towards the periphery and the metaxylem (the later-formed xylem) lies towards the center (pith). Hence, the youngest lies closest to the center in this type of arrangement. So, the answer is, “Exarch.”
