Solution

The correct option is C Presence of 15-20 vasuclar bundles
Vascular bundles of dicot root are described as radial. There are four to six bundles each of xylem and phloem occurring alternately. Xylem is described as exarch. Pith is absent in the older root. Secondary growth is present in dicots and absent in monocots. Thus, option C is correct.
