A Correct answer
Explanation

All three statements about Kant's nebular hypothesis are correct. Kant did incorporate Newton's law of gravitation to explain particle attraction and disk formation. He accepted the principle of conservation of angular momentum. Although Laplace later proposed a similar nebular hypothesis, Kant is widely credited as the original propounder of this theory of Earth's origin from a rotating nebula.
