Answer B

The volume of the sphere is $\frac{4}{3} * \pi * r^3$ so if diameter is $1$ unit than Radius is 0.5 unit so

Volume = $ \frac{4}{3} * 3.14 * (0.5)^3$ = 0.5233 $unit^3$

volume of the cube with side 1 unit = $(side)^3 $= $(1)^3 $ = 1 $unit^3$

so the volume of a sphere of diameter 1 unit is **less** than the volume of a cube of side 1 unit.
