How old is the Sun?
A
2 billion years
B
4.6 billion years
C
10.000
D
1.000
Explanation: 

Detailed explanation-1: -The Sun formed about 4.6 billion years ago in a giant, spinning cloud of gas and dust called the solar nebula. As the nebula collapsed under its own gravity, it spun faster and flattened into a disk.

Detailed explanation-2: -Or not so much? Our Sun is 4, 500, 000, 000 years old. That’s a lot of zeroes. That’s four and a half billion.

Detailed explanation-3: -How the sun formed. The sun was born about 4.6 billion years ago. Many scientists think the sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust known as the solar nebula.

Detailed explanation-4: -The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.

Detailed explanation-5: -In a few billion years, the sun will become a red giant so large that it will engulf our planet. But the Earth will become uninhabitable much sooner than that. After about a billion years the sun will become hot enough to boil our oceans. The sun is currently classified as a “main sequence” star.
