A block of mass $$\mathrm{l} \mathrm{kg}$$ is fastened to a spring of spring constant of $$100 ~\mathrm{Nm}^{-1}$$. The block is pulled to a distance $$x=10 \mathrm{~cm}$$ from its equilibrium position $$(x=0 \mathrm{~cm})$$ on a frictionless surface, from rest at $$t=0$$. The kinetic energy and the potential energy of the block when it is $$5 \mathrm{~cm}$$ away from the mean position is

A
$$0.375 \mathrm{~J}, 0.125 \mathrm{~J}$$
B
$$0.125 \mathrm{~J}, 0.375 \mathrm{~J}$$
C
$$0.125 \mathrm{~J}, 0.125 \mathrm{~J}$$
D
$$0.375 \mathrm{~J}, 0.375 \mathrm{~J}$$
