In a monoclinic unit cell the relation of sides and angles are respectively

Options

A. `a ne b ne c, alpha = gamma = 90^(@), beta ne 90^(@)`.
B. `a = b = c, alpha = beta = gamma = 90^(@)`
C. `a = b = c, alpha = beta = 90^(@), gamma =120^(@)`
D. `a ne b = c, alpha = beta = gamma = 120^(@)`

Answer

A

Explanation

For monoclinic crystal, `a ne b ne c, alpha = gamma = 90^(@), beta ne 90^(@)`.
