Seven people I, J, K, L, M, N and O, are sitting in a straight row, facing the north. Only five people sit to the left of M. J sits third to the left of ( O . O ) is not an immediate neighbour of M. K sits to the immediate right of N. I sits fourth to the right of J. Who sits at the extreme right end of the row?
