The position of a particle moving in the $xy$-plane at any time $t$ is given by $x = (3t^2 - 6t) \text{ m}$ and $y = (t^2 - 2t) \text{ m}$. Select the correct statement about the moving particle from the following:
- AThe acceleration of the particle is zero at $t = 0 \text{ s}$.
- BThe velocity of the particle is zero at $t = 0 \text{ s}$.
- CThe velocity of the particle is zero at $t = 1 \text{ s}$.
- DThe velocity and acceleration of the particle are never zero.
