Solution

The correct option is C Mesarch
Endarch:- protoxylem is formed toward the centre (pith) and metaxylem is formed away from the centre (periphery). Example:- stem of Angiosperm and Gymnosperm.
Exarch:- protoxylem is formed towards the periphery and metaxylem is formed towards the centre. Ex. Roots
Mesarch:-Elements of metaxylem are formed on both sides of the elements of protoxylem.Ex. fern rhizome.
So correct answer is C (mesarch).
