Which of the following option(s) is//are incorrect if an arrangement is formed by two different atoms A and B such that B forms cubic close packing and A atoms occupy all the octahedral voids without causing any distortions.
[Given : Edge length of cube = a, Radius of atom A= r_(a), Radius of atom B = r_(b)]

Options

A. `4r_(b) = sqrt(2a)`
B. `r_(a) + r_(b) = sqrt(2).r_(a)`
C. The arrangement can be viewed as A atoms forming cubic packing and B atoms occupying all octahedral void without any distortions.
D. Distance between two nearest atoms of A will be equal to twice the radius of atom of B.
