The motion of a particle moving along x-axis is represented by the equation `(dv)/(dt)=6-3v`, where v is in m/s and t is in second. If the particle is at rest at t = 0 , then
A. The speed of the particle in 2 /s when the acceleration of particle is zero
B. After a long time the particle moves with a constant velocity of 2 m/s
C. The speed is 0.1 m/s, when the acceleration is half of its initial value
D. The magnitude of final acceleration is `6m//s^(2)`
