A. Copernicus
B. Einstein
C. Newton
D. Galileo

Answer 1

Hint: The view that earth and other planets revolve around the sun is the Heliocentric astronomical model. Aristarchus, Nicolaus Copernicus, William Herschel, Freidrich Bessel, Galileo Galilei and other astronomers and scientists worked on the revolution of planets around the sun.

Complete answer: Through the model of Heliocentrism it was concluded that the Earth and other planets revolve around the sun at the center of the Universe. This model was earlier opposed to geocentrism, which placed the Earth at the center. In the 16th century the mathematical model of the heliocentric system was presented by the astronomer, Catholic cleric and Mathematician Nicolaus Copernicus which was known as the Copernican Revolution. He concluded that earth revolves around the sun not the sun revolves around the earth.

Looking at the options given:
Option A. Copernicus was the one who in the 16th century concluded that earth revolves around the sun. This is the correct answer.

Option B. Einstein is famous for his theory of relativity. It is an incorrect option.

Option C. Newton discovered the laws of gravity and motion. It is an incorrect option.

Option D. Galileo Galilei was an astronomer who invented the first telescope in 1609. It is an incorrect option.

So, the correct answer is option A.

Note: Copernicus also argued that earth turned daily on its axis and that gradual shifts of this axis accounted for the changing seasons.
