The sun burns by means of a nuclear reaction, fusion to be precise, which uses up the hydrogen in the sun. This is a different reaction from regular combustion.

Burning is generally a chemical process where certain atoms or molecules like oxygen and hydrogen are combined to form other molecules, like water. Heat and light energy are also produced. The chemical processes involve the electrons of the combining atoms and molecules.
The heat (and light) produced by the Sun comes from an entirely different process where the basic structures of the atoms themselves are changed and a tiny bit of the matter involved is transformed to energy. This thermal-nuclear process involves the protons and neutrons within the nucleus of the atoms

They all got it right!! The "burn" of the sun is not a chemical reaction where a substance is being oxidised by oxygen. The process taking place is a nuclear one fueled by coligative energy of the neutrons and protons

The reaction occuring in sun is not oxidation where oxygen is required. It is nuclear fusion reaction in which two hydrogen atoms combine to form Helium and tremendous amount of energy.

The sun needs no oxygen. It is not a combustion reaction.
The energy of the sun is from nuclear fusion reactions of heavy hydrogen atoms.

Different type of reaction. Burning is combining with oxygen, the sun's reaction is a thermonuclear one. No oxygen required.

It's not burning. The sun's light and heat are the result of a nuclear reaction in its core. It is not nuclear fission, it is actually nuclear fusion. Hydrogen isotopes (tritium and deturium) fuse to form Helium-4 and give off massive amounts of heat and light in the process as well as neutrons.

All of the above - the sun is having a nuclear reaction. No oxyegen is required for this process.

Burn is the incorrect term to use for the H+H to He reaction that produces heat and a visable 'fire' It's all nuclear baby!

Fusion of hydrogen to form helium gives off a lot heat that ignites the hydrogen.
