A crystal is made of particles \( A \) and \( B \). \( A \) forms fcc packing and \( B \) occupies all the octahedral voids. If all the particles along the plane as shown in figure are removed, then, the formula of the crystal would be:
(a) \( A B \)
(b) \( A_{5} B_{7} \)
(c) \( A_{7} B_{5} \)
(d) none of these
