Answer : Option f) Either c or d
Explanation :
The direction of force on wire can be found using Flemings Left hand rule .
In the given situation , force on wire is coming out of the plane that is it is along +z direction , now changing the magnitude of current or field only changes the magnitude on force and does not effect its direction.
Direction changes only if we change direction of either the current or Magnetic field .
Either we flip the direction of field or current in both case using flemings left hand rule we can see that force acts along -z direction i.e. is its direction changes by 180o .
