Fortunately, there were 4 students only and 3 of them are liars.
Let us assume that Ku took it:
Ku=Mu took it=wrong
Lu=I did not take it=right
Mu=Lu is lying=wrong
Nu=Mu is lying=right
Let us assume that Lu took it:
Ku=Mu took it=wrong
Lu=I did not take it=wrong
Mu=Lu is lying=wrong
Nu=Mu is lying=right
Let us assume that Mu took it:
Ku=Mu took it=right
Lu=I did not take it=right
Mu=Lu is lying=wrong
Nu=Mu is lying=right
Let us assume that Nu took it:
Ku=Mu took it=wrong
Lu=I did not take it=right
Mu=Lu is lying=wrong
Nu=Mu is lying=right
Therefore, the answer is...
Added:
In case, there is one liar only among them, the answer would be...

Every living thing has no choice but to execute its pre-programmed instructions embedded in it (known as instincts).
But only a human may have the freedom and ability to oppose his natural robotic nature.
But, by opposing it, such a human becomes no more of this world.
