A car moving along a straight road at a speed of $$u$$ m/s applies brakes at $$t = 0$$ second. The ratio of distances travelled by the car during $$3^{rd}$$ and $$8^{th}$$ second is $$15 \colon 13$$. The car covers a distance of 0.25 m in the last second of its travel. Therefore, the acceleration $$a$$ (in $$\text{m/s}^2$$) and the speed $$u$$ (in m/s) of the car are respectively

A

$$-0.1$$, 16

B

$$-0.2$$, 12

C

$$-0.5$$, 20

D

$$-0.1$$ , 16
