Answer:

D Dark Energy

Explanation:

The expansion of the universe is explained on the basis of dark energy.

A force that is responsible for the expansion of the universe is named as the Dark energy. It is only a hypothetical form of energy. It seems to oppose gravity by exerting a negative and repulsive pressure.

Accelerated expansion of the universe is caused by the dark energy. Dark energy contributes to atleast 68% of the total energy that exists in the present day observable universe. These are details that are presented by the Standard model of Cosmology.

Dark matter neither emits nor absorbs light. It exerts immense gravity.
