Four of the following five are alike in a certain way and hence form a group. Who among the following one who does not belong to that group?

We have, G sits second to the left of K. Two persons are sitting between K and J.  F and J are sitting adjacent to each other. From the above condition, there are three possibilities Again we have,  The number of persons sitting between K and F is the same as between K and E. From the above condition, case1 gets eliminated. Again we have,  H sits exactly in the middle of I and F.  F sits fifth to the left of E.  I does not sit third to the right of J.  Not more than one person sits between H and F. From the above condition, case2 gets eliminated. Case 1a shows the final arrangement
