For a cubic crystal structure which one of the following relations indicating the cell characteristics is correct ?

a $$ \ne $$ b $$ \ne $$ c and $$\alpha $$ = $$\beta $$ = $$\gamma $$ = 90^o

a = b = c and $$\alpha $$ $$ \ne $$ $$\beta $$ $$ \ne $$ $$\gamma $$ = 90^o

a = b = c and $$\alpha $$ = $$\beta $$ = $$\gamma $$ = 90^o

a $$ \ne $$ b $$ \ne $$ c and ;$$\alpha $$ $$ \ne $$ $$\beta $$ $$ \ne $$ and $$\gamma $$ = 90^o
