Four of the following five are alike in a certain way based on their positions in the given arrangement and so form a group. Which is the one that does not belong to that group ?

Only three people sit between N and O, => O and N sit opposite each other.

K sits second to the right of L. Also, K is not adjacent to O, => only 2 positions for O are possible ($$\because$$ it is also opposite to N), let it be to the immediate left of L.

=> N sits to the immediate right of K.

J sits to the immediate right of M and P is not adjacent to O, => M sits second to the right of N and J to the immediate left of O.

Also, P is not an immediate neighbour of K, => P sits between M and N and the vacant place, i.e. to the immediate right of L is taken by Q.

Apart from MLO, all the mentioned names are adjacent to each other.

=> Ans - (D)
