Four of the following five are alike in a certain way and hence form a group. Find the one that doesn’t belong to that group.

Study the following information carefully and answer the questions given below. Eight persons A, C, E, J, L, N, P and R are sitting on a circular table such that four persons are facing inwards while four persons are facing outwards alternatively, but not necessarily in the same order. P sits third to the left of R where as N sits second to the right of R. Two persons are sitting between N and
L. The number of persons between L and P is same as the number of persons between R and A, when counted from the right of L and
A. J neither sits facing outside nor adjacent to N but adjacent to
C.
