Explanation:

Pair 1 is correct: Nebular Hypothesis - This hypothesis was first proposed by Immanuel Kant. The nebular hypothesis is a widely accepted scientific explanation for the formation of our solar system. It proposes that our solar system originated from a giant cloud of gas and dust called a nebula, and planets were formed out of gaseous matter associated with the Sun in the early stages. Pair 2 is correct: Big Bang theory- Edwin Hubble gives evidence about the expanding universe. The Big Bang theory is the prevailing scientific explanation for the origin and evolution of the universe. It suggests that the universe began as a singularity—an infinitely hot and dense point that exploded violently, resulting in the formation of the expanding Universe. Pair 3 is correct: Binary Theory- This theory, also called the Planetesimal hypothesis, was given by Chamberlain and Moulton in 1900. According to this theory, a star collided with the Sun. As a result, some matter separated from the Sun. After the star moved away, the separated material gradually formed the planets.
