A current carrying long solenoid is placed on the ground with its axis vertical. A proton is falling along the axis of the solenoid with a velocity $v$. When the proton enters into the solenoid, it will

  • A

    Be deflected from its path

  • B

    Be accelerated along the same path

  • C

    Be decelerated along the same path

  • D

    Move along the same path with no change in velocity
