What is the position of O with respect to D?

We have: N sits third to right of D, who sits facing Q. No person sits left of Q. That means, in case (1) Q sits at left end of Row1, in case (2) Q sits left end of Row3. L sits third to right of K. Neither L nor K sits at end of the row. K sits facing R, who sits immediate right of G. That means, in case (1a) L sits immediate left of D, in case (1b) L sits immediate right of D, in case (2a) L sits immediate left of D, in case (2b) L sits immediate right of D. Based on above given information we have: Case-2a Again, we have: The one who sits facing Y, sits second to right of M. M and K doesn’t sit together. Y neither sits adjacent to Q nor sits adjacent to N. That means, in case (1a) M sits immediate right of Q, in case (1b) M sits immediate left of N, in case (2a) M sits immediate right of M, in case (2b) M sits immediate left of N. One person sits between P and F, who sits facing A. That means, in case (1b) A sits immediate right of R, in case (2b) A sits immediate right of A, case (1a) & case (2a) are not valid. X sits immediate left of J, who sits facing south. That means, in case (2b) X sits immediate right of Y, case (1b) is not valid. Z sits in any row north of O’s row. That means, in case (2b) Z sits immediate left of Y and O sits immediate left of L. Based on above given information we have final arrangement as follows: Case (1a) & case (2a) are not valid as one person sits between P and F, who sits facing A, case (1b) is not valid as X sits immediate left of J, who sits facing south.
