Answer:
Nebular
Step-by-step explanation:
The theory that suggests that the sun, planets, and other celestial bodies of the solar system came from a cloud of dust and gas is known as the Nebular theory. Nebular theory states that our solar system was formed from a cloud of gas and dust known as the solar nebula. According to the theory, the solar nebula was a giant rotating cloud composed mostly of hydrogen and helium, along with other elements. Over time, gravity caused the cloud to collapse, and the resulting increase in pressure and temperature triggered the formation of the sun in the center of the nebula. As the nebula continued to collapse, it formed a spinning disk of gas and dust, which eventually formed the planets, moons, asteroids, and other objects in our solar system.So, the correct answer is option (d) Nebular theory.
