Heya..!

first, identify the labelled parts.

1 is phloem

2 is Xylem

3 is medullary rays and pith

you might be already knowing that xylem transports water and minerals from roots to required parts..

phloem carries organic materials from leaves to required parts (top to bottom)
sometimes from storage organs to required parts( bottom to top)

medullary rays& pith play a major role in radial conduction..


So, correct option is B) 2 only.

HOPE THIS HELPS YOU ❤
