hope you pass
its right :)

The two most abundant types of baryonic matter in the universe are helium (A) and hydrogen (C). This can be determined by studying the composition of stars, galaxies, and the cosmic microwave background radiation.
According to measurements made by the Wilkinson Microwave Anisotropy Probe (WMAP), dark energy (D) is actually the most plentiful material in the universe, not baryonic matter. Dark energy is a mysterious form of energy that is believed to be responsible for the accelerating expansion of the universe.
The gravitational pull of dark matter causes baryonic gas and dust to clump together. Dark matter is a type of matter that does not interact with electromagnetism and is mainly detected through its gravitational effects on other matter.
