No force acts on it. It will not be pushed.

Explanation:

The proton moving in the - X direction implies its velocity is in the - X direction and the magnetic field is given to be in the + X direction. So the angle between them is 180 degrees. So no force acts on the proton, since the velocity and magnetic field are anti parallel.

Magnetic force is given by the equation F = q v B sin theta where theta is the angle between the velocity and the magnetic field. This force will be a maximum if they are perpendicular to each other.
