Gridling experiment cannot be permormed in sugar cane ecause

a-it cannot withstand injury

b-vascular bundles in it are scattered

c-phloem in it is situated internal to xylem

d-sugar cane plants are too delicate

which one is correcct?

Option (b) is correct.

Sugarcane plant is monot so in it vascular bundles are scattered. For girdling experiment we have to remove phloem which is possible in dicots because in them vascular bundles are arranged in the outer ring, but in monocots vascular bundles are scattered so it is very difficult to remove phloem from each vascular bundle, that is why sugarcane is not a good choice for girdling experiment.
