Correct option is A)

When the particle is released from rest, it starts to move along the fields due to application of electric field. 
The magnetic force acting on a moving charged particle is given by 
Since velocity and magnetic fields are parallel, no magnetic force acts on the particle, hence it continues to move in a straight line along with constant acceleration.
