PZ is an immediate neighbor of both KZ and RZ, means PZ is seated between KZ and RZ. OZ is second to the right of KZ. NZ is an immediate neighbor of both LZ and QZ. This means QZ/LZ will occupy either of the immediate left and right seats to NZ. Final arrangement is as shown below: From the above arrangement, it is clear that MZ is exactly between KZ and OZ. Hence, the correct answer is (B).
