An electron having a charge \( -e \) moves with a velocity \( \nu \) in positive \( X \)-direction. An electric field exist in region along positive \( Y \)-direction and a magnetic field exist in the region along negative \( X \)-direction. The force on the electron acts in :
(A) Positive direction of \( Y \)-axis
(B) Negative direction of \( Y \)-axis
(C) Positive direction of \( Z \)-axis
(D) Negative direction of \( Z \)-axis
