Select the correct statement(s):
(a) A NaCl type \( A B \) crystal lattice can be interpreted to be made up of two individual fcc type unit lattice of \( A^{+} \)and \( B^{-} \)fused together in such a manner that the corner of one unit lattice becomes the edge centre of the other
(b) In a fcc unit cell, the body center is an octahedral void
(c) In an scc lattice, there can be no octahedral void
(d) In an scc lattice, the body center is the octahedral void
