A particle is moving on a straight line. The distance $$\mathrm{S}$$ travelled in time $$\mathrm{t}$$ is given by $$\mathrm{S=a t^2+b t+6}$$. If the particle comes to rest after 4 seconds at a distance of $$16 \mathrm{~m}$$. from the starting point, then the acceleration of the particle is.

A
$$\frac{-3}{4} \mathrm{~m} / \mathrm{sec}^2$$
B
$$\frac{-1}{2} \mathrm{~m} / \mathrm{sec}^2$$
C
$$-1 \mathrm{~m} / \mathrm{sec}^2$$
D
$$\frac{-5}{4} \mathrm{~m} / \mathrm{sec}^2$$
