All the songs could be played immediately after K except one. What is that song?

A jazz group plans to play six songs during a show which are in the order of J, K, L, M, N, O. Each song will be played exactly thrice. The order in which the songs are to be played is subjected to the following conditions. N must be played before J and before O. M must be played later than J. K must be played third..

Yes, it's correct choice

In the sequence M J K O L N

N is played before J and O which doesn't satisfy the conditions

N must be played before J and before O

N J O 

M must be played later than J

N J O M or N O J M

K must be played third in piece 

One of the possibilities is ||||||| |---|---|---|---|---|---| |1|2|3|4|5|6| |N| L|K|J|O|M|

N is played before K   ||||||| |---|---|---|---|---|---| |1|2|3|4|5|6| |N|L|K|J|M|O| |N|J|K|L|M|O|

So, N can't  be played after K. It should be played before K .
