A particle of mass 10 g starts from rest at $$t = 0$$ s from a point (0 m, 4 m) and gets accelerated at $$0.5\ \text{m/s}^2$$ along $$x - \sqrt{3}y + 4\sqrt{3} = 0$$ in XY plane. The angular momentum of the particle about the origin (in SI units) at $$t = 2$$ s is

A

$$-0.01\sqrt{3}\,\hat{k}$$

B

$$-0.02\sqrt{3}\,\hat{k}$$

C

zero

D

$$-20\sqrt{3}\,\hat{k}$$
