The Correct Option is D

Solution and Explanation

Concept: Polymorphism means the ability of a substance to exist in more than one crystalline form while having the same chemical composition.

Step 1:
Quartz is a crystalline form of silica: \[ SiO_2 \]

Step 2:
Silica can exist in different polymorphic forms depending on temperature and structure.

Step 3:
The main polymorphic forms of silica are: \[ \text{Quartz, Tridymite, and Cristobalite} \]

Step 4:
Therefore, the total number of important polymorphic forms of quartz/silica is: \[ 3 \] Hence, \[ \boxed{3} \]
