Option C. KE decreases, GPE increases

What is the GPE of the comet?

The GPE of the comet is given by, U(r) = -GMm/r, where M is the mass of the sun, and m is the mass of the comet.

The total energy E of the comet remains constant.

We know, E = K + U  ⇒  K = E - U. So, if U increases K decreases.

As the comet moves from B to C, the distance r between the comet and the sun increases.

When r increases U(r) increases according to the above equation, it becomes more positive. So, the GPE of the comet increases as it moves from B to C. KE, according to the energy relation, thus, decreasing during the same course of motion.

Therefore, as the comet moves from B to C, its KE decreases, and its GPE increases.
