- D(A) (i) Monarch (ii) Exarch (B) (i) Dicot root
Correct answer
C. (A) (i) Tetrarch (ii) Exarch (B) (i) Monocot root
Step-by-step solution
In roots, protoxylem lies towards periphery and metaxylem towards the center. This condition of the vascular bundle is called exarch; hence, cicer root has exarch condition. A well-developed pith is found in monocot root and dicot stem.
