(d) Rachis and leaflet
Explanation:
The rachis and leaflet have diploxylic vascular bundles. At the region of the stem cortex, the leaf trace has only centrifugal xylem, hence, it is endarch. These traces enter the leaf as the rachis separates, the centripetal xylem appears and it is in the exarch condition. The leaflet has a single midrib bundle and is in the diploxylic condition.
