The correct option is D Upward
This question can be solved by using Fleming’s Left Hand Rule. We know that the direction of the current is opposite to the direction of electron’s movement and hence, it would be the same as the direction of proton’s movement. So, the direction of current is towards west. As per Fleming’s Left-Hand Rule; the middle finger shows the direction of the current, the forefinger shows the direction of the magnetic field and the thumb shows the direction of motion. Here, the deflection is towards the north, and hence, the direction of the magnetic field would be in the upward direction.
