Solution

The correct option is A center; periphery
The first formed xylem elements are called proto-xylem and the later formed xylem is called meta-xylem.
In both monocot and dicot stems, the proto-xylem lies towards the center (pith) and the meta-xylem lies towards the periphery. The stem which exhibits this type of xylem arrangement is said to be endarch.
