Solution

The correct option is A Calcium
Calcium is required by meristematic and differentiating tissues. During cell division it is used in the synthesis of cell wall, particularly as calcium pectate in the middle lamella. It is also needed during the formation of mitotic spindle. The deficiency of calcium results in death of leaf, stem and root apices.
