The vertical deflection of an electron beam on the screen of a CRO is measured to be 8 mm. Now, the potential difference between the Y-plates is doubled, and simultaneously the pre-accelerating anode voltage is reduced to half of its previous value. Then, the vertical deflection of the beam on the screen would become

(A) 64 mm (B) 32 mm (C) 8 mm (D) 1 mm
