Solution
The correct option is C Root cap, cell division, cell enlargement, cell maturation
The four zones from the root tip are root cap, cell division, cell enlargement, cell maturation. Each zone has primary meristematic tissues with different functions. Root cap has parenchyma at tip. Zone of cell division has apical meristem, where the cells divide every 12-36 hours. Zone of elongation or enlargement, where cells get longer. Zone of maturation, which become specific cell types like epidermal cells and cortex.
So, the correct answer is 'Root cap, cell division, cell enlargement, cell maturation'
