Motion in A Straight Line

Question: The position of a particle moving in the xy-plane at any time \[t\] is given by \[x = (3{t^2} - 6t)\] metres, \[y = ({t^2} - 2t)\] metres. Select the correct statement about the moving particle from the following



1) The acceleration of the particle is zero at \[t = 0\] second
2) The velocity of the particle is zero at \[t = 0\] second
3) The velocity of the particle is zero at \[t = 1\] second
4) The velocity and acceleration of the particle are never zero
