Answer 1

The correct order for the formation of the Universe is a, b, c, d: Big Bang, Formation of Stars and Galaxies, Cosmic Microwave Background Radiation, Formation of Elements.

Step-by-step explanation:

The correct order for the formation of the Universe is a, b, c, d.

1. The Big Bang is believed to have occurred approximately 13.7 billion years ago and marks the beginning of the Universe.
2. Following the Big Bang, the formation of stars and galaxies took place. These celestial bodies were formed from the gravitational collapse of dense matter.
3. After the formation of stars and galaxies, the Cosmic Microwave Background Radiation (CMB) was emitted when the universe cooled enough for hydrogen atoms to form and become transparent to light.
4. The formation of elements occurred through nuclear reactions within stars, where hydrogen fusion produced heavier elements such as helium and lithium.
