C
States that all of the current and past matter in the Universe came into existence at the same time after a big explosion
D

Explanation: 

Detailed explanation-1: -The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now-and it is still stretching!

Detailed explanation-2: -The Big Bang theory is an explanation of the early development of the Universe. According to this theory the Universe expanded from an extremely small, extremely hot, and extremely dense state. Since then it has expanded and become less dense and cooler.

Detailed explanation-3: -Our universe began with an explosion of space itself-the Big Bang. Starting from extremely high density and temperature, space expanded, the universe cooled, and the simplest elements formed. Gravity gradually drew matter together to form the first stars and the first galaxies.

Detailed explanation-4: -According to the Big Bang theory, the expansion of the observable universe began with the explosion of a single particle at a definite point in time. Georges Lemaître, (1894-1966), Belgian cosmologist, Catholic priest, and father of the Big Bang theory.

Detailed explanation-5: -Smashing together lead particles at 99.9999991 percent the speed of light, scientists have recreated the first matter that appeared after the Big Bang. Out of the wreck came a primordial type of matter known as quark-gluon plasma, or QGP.
