Explanation:

Only 2nd statement is correct.

The Sun is the star at the center of the Solar System. It is a nearly perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. It is by far the most important source of energy for life on Earth. Its diameter is about 109 times that of Earth, and its mass is about 330,000 times that of Earth, accounting for about 99.86% of the total mass of the Solar System. About three quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron.

It is true that all the planets of solar system shine by the reflected light of the sun but the stars have their own light so 1 is incorrect

Sun is the heaviest body of the solar system accounting for 99% of its total mass so 3 is incorrect

Moon due to its proximity to earth exerts as much as 2.2 times more influence on the tides on earth as compared to sun so 4 is incorrect
