The current understanding of dark matter is largely theoretical due to its nature of not directly interacting with electromagnetism. It can be inferred to exist due to its gravitational effects, representing about 27% of the universe's mass-energy composition. The key candidate for it is Weakly Interacting Massive Particles, suggested by the Supersymmetry theory.
Our current understanding of the nature of dark matter is largely theoretical, as dark matter does not interact with the electromagnetic force and cannot be seen directly with telescopes. However, it is inferred to exist due to its gravitational effects on galaxies and galaxy clusters. Dark matter constitutes about 27% of the universe's mass-energy composition, vastly outweighing ordinary matter. The leading candidate for dark matter is currently the Weakly Interacting Massive Particles, or WIMPs. The existence of WIMPs is suggested by the Supersymmetry theory in particle physics, and several experiments are ongoing to detect WIMPs directly.

warm, salty water
B.
warm water with no salt
C.
cold water with no salt
D.
cold, salty water
B, cold with a high salt content, I believe. Since density is mass divided by volume, adding salt would increase mass. Temperature is related to kinetic energy and the distance between molecules/atoms of a substance. The hotter the substance, the more distance there is between particles. Generally cold water is more dense. Hope i helped :D
