The figure shows the path of a planet orbiting the Sun. The three areas shaded in gray have equal areas.

According to Kepler’s second law, which conclusion is supported by the data?

• The time intervals from A to B, C to D, and E to F are all equal.

• The time interval from A to B is twice the interval from E to F.

• The distance intervals from A to B, C to D, and E to F combine to be equal to one half of a full orbit.

• The distance intervals from C to D and from E to F combine to be equal to the time interval from A to B.
