Statement 1 is correct: Immanuel Kant proposed the Nebular Hypothesis theory. The hypothesis considered that the planets were formed out of a cloud of material associated with a youthful sun that was slowly rotating.

Statement 2 is correct: The Binary Theory posits that the Sun had a companion star, and their gravitational interaction led to the formation of the planets. This theory attempts to explain certain features of the solar system.

Statement 3 is correct: The tidal theory which was proposed by Jean and Jeffery says that when a star passes close to the Sun, its gravitational force causes the Sun to stretch the ejected material. This ejected material later condensed and formed the planets of our solar system.
