Six friends B, C, L, M, N and O are sitting around a circular table facing the center of the table. L sits fourth to the right of O. Only one person sits between M and N when counted from the left of M. L sits third to the left of C. B is an immediate neighbor of C and N.

Correct answer
Three
Why this answer is correct
-
Since all persons face the centre: right = counter-clockwise (CCW), left = clockwise (CW). Fix O at pos(1). L sits fourth to the right of O (CCW): O(1) → 2 → 3 → 4 → L(5).
-
L sits third to the left of C. This means C sits third to the right of L (CCW): L(5) → 6 → 1 → C(2). So, C is at pos(2).
-
B is an immediate neighbor of C and N. Since O is at pos(1), B must be at pos(3) to be next to C, and N must be at pos(4) so that B is also next to N.
-
The last person M fills the remaining pos(6). This fits the condition: one person (L) sits between M and N from the left of M (CW): M(6) → L(5) → N(4).
To find the number of people between L and B when counted from the left of B (clockwise direction): Starting from B(3) going CW: C(2), O(1), M(6), and then we reach L(5). The people sitting between them are C, O, and M, which is a total of three people.
Hence, the correct answer is 'Option 1'.
