The displacement \( (x) \) of a particle depends on time \( t \) as \( x=\alpha t^{2}-\beta t^{3} \). Choose the incorrect statements from the following.
(a) The particle never returns to its starting point
(b) The particle comes to rest after time \( \frac{2 \alpha}{3 \beta} \)
(c) The initial velocity of the particle is zero
(d) The initial acceleration of the particle is zero
