Quantity of erystallization centres in crystallization may increase a) insert imitation of crystallization b) use mechanical mixing: c) change cooling rate; d) all of the above are correct.

d) All of the above

Explanation: Crystallization is the process in which a solid crystalline structured material is obtained from the liquid substance. the quantity of crystallization center in crystal may increase due to several reasons like changing the cooling rate or mechanical mixing of the substances or imitation of crystals etc.

These processes end up adding mineral atoms to get attached to the center of crystal and hence increasing the size. Thus, the correct option is option (d).
