(D) The $CSA$ (Curved Surface Area) of a cylinder is given by the formula $2 \pi r h$.The volume of a cylinder is given by the formula $\pi r^{2} h$.According to the problem,the $CSA$ and the volume are numerically equal:$2 \pi r h = \pi r^{2} h$Dividing both sides by $\pi r h$ (assuming $r \neq 0$ and $h \neq 0$):$2 = r$Therefore,the radius of the cylinder is $2$ units.
