Dear nitin,

a) statement is true and magnetic force can be zero that depends on the direction of velocity and magnetic field.

We are all IITians and here to help you in your IIT JEE preparation.

All the best.

option d is correct because force depends on angle  so force can be zero as well as different for diff angles
