Q. Tetragonal crystal system has the following unit cell dimensions
A) $a = b = c$ and $\alpha = \beta = \gamma = 90{^\circ}$
B) $a \neq b \neq c$ and$\ \alpha = \beta = \gamma = 90{^\circ}$
C) $a = b \neq c\$and $\alpha = \beta = \gamma = 90{^\circ}$
D) $a = b \neq c$ and $\alpha = \beta = 90{^\circ}$ and $\gamma = 120{^\circ}$
Explanation
The correct answer is Option C: $a = b \neq c\$and $\alpha = \beta = \gamma = 90{^\circ}$.
