The most significant change in the comet's energy as it moves from point D to point A KE increases, GPE decreases.Option C is correct.
What are comets?
Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ice.
They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a plane.
As the comet transitions from point D to point A, the biggest energy shift is seen. GPE declines as KE rises. The right answer is C.
Hence option C is correct.
