The correct statement is:
**The comet’s kinetic energy increases.**
As the comet approaches the Sun, it is drawn in by the Sun's gravitational pull, causing it to speed up. Kinetic energy is given by the equation \( KE = \frac{1}{2} mv^2 \), where \( m \) is mass and \( v \) is velocity. As the velocity increases, the kinetic energy also increases.
