Situation (I):
In whatever time Karan covers a distance of 100 m, Arjun covers 90 m in the same time.

Situation (II):
Now Karan is 10 m behind the starting point. Once again to cover 100 m from this new point Karan will be taking the same time as before. In this time Arjun will be covering 90 meters only.
This means that now both of them will be at the same point, which will be 10 meters away from the finish point.
Since both of them are required to cover the same distance of 10 m now and Karan has a higher speed, he will beat Arjun.

No need for calculations as option (D) is the only such option.
