All the persons are facing inside except N.
Hence, option A.
P is 2
nd to the right of T so either T is facing inside or outside.
Case 1: If T is facing inside: If T is facing inside then S is facing outside and then R is facing inside so we get this-
N, P, R and T are facing inside and M, O, Q and S are facing outside.
Two persons are sitting between P and O.
Q is 2
nd to the right of O. N is not neighbor of T. M is 2
nd to the right of N.
R is 2
nd to the left of S but not neighbor of N. R’s both neighbours are facing outside from the centre. In both cases, R’s both neighbors cannot be facing outside so this case gets rejected.
Case 2: If T is facing outside: If T is facing outside then S is facing inside and then R is facing outside so we get this-
N, P, R and T are facing outside and M, O, Q and S are facing inside.
Two persons are sitting between P and O.
Q is 2
nd to the right of O. N is not neighbor of T. M is 2
nd to the right of N.
R is 2
nd to the left of S but not neighbor of N. As S is facing inside so in case 2A, R must be neighbor of N so case 2A gets rejected. In case 2B, R is neighbor of P and T and S is immediate neighbor of M.
Here is the final arrangement:
