Study the following information carefully and answer the questions given below :
Nine persons, B, C, D, E, L, M, N, 0 and P are seated in a straight line facing north, with equal distance between each other, but not necessarily in the same order. As many people sit to the left of E as to the right of E. Only one person sits between E and 0. L sits third to the left of P. P is not an Immediate neighbour of 0. Neither P nor D sits at any of the extreme ends of the line. Only three persons sits between B and C.. B is not an Immediate neighbour of E. The number of people sitting between B and E is double as that between E and N.
Four of the following five are alike in a certain way based on the given arrangement and thus form a group. Which is the one that does not belong to that group?
As many people sit to the left of E as to the right of E, => E sits in the middle.
Only one person sits between E and O
Case 1 : O sits second to the left of E.
L sits third to the left of P and P is not an Immediate neighbour of O. Also, P does not sit at any end.
=> L sits to the immediate left of E and P sits second to the right of E.
Only three persons sits between B and C and B is not an Immediate neighbour of E, => C sits to the immediate right of E and B sits fourth to the left of C.
Since, D does not sit at any end, => D sits to the immediate right of P.
Also, there are two people between B and E, => there should be only 1 person sitting between E and N, which is not possible as shown :

Case 2 : O sits second to the right of E.
L sits third to the left of P and P is not an Immediate neighbour of O. Also, P does not sit at any end.
=> P sits to the immediate left of E and L sits at extreme left end.
Only three persons sits between B and C and B is not an Immediate neighbour of E, => C sits to the immediate right of E and B sits fourth to the left of C.
The number of people sitting between B and E is 2, so number of people sitting between E and N should be 1, => N sits second to the left of E.
Since, D does not sit at any end, => M sits at right end and D to its immediate left. The arrangement :

The groups mentioned above are immediate neighbors, only exception is DB, who are not neighbors.
=> Ans - (E)
