The correct statement that describes Kepler’s third law of orbital motion is:

**The square of the orbital period is proportional to the cube of the semi-major axis.**

This means that if you square the orbital period of a planet (T²), it will be proportional to the cube of the semi-major axis of its orbit (a³). In mathematical terms:

\[ T^2 \propto a^3 \]

where T is the orbital period and a is the semi-major axis.
