The correct response is:

the time the planet takes to sweep out the areas

This is a reflection of Kepler's Second Law (the Law of Areas), which states that a line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time, meaning that the time it takes the planet to sweep out the areas remains constant.
