Why not any of the other options?

Because the core of the sun consists H and He. The Hydrogen will be converted into the Helium due to this the sun heat.

How does hydrogen convert into helium?

Generally proton and neutron collide with each other and make deuterium (isotope of hydrogen). Similarly most of deuterium combine to form helium in the sun. So sun is abundant with helium.

Neutron proton attract with each other. So that's by hydrogen convert into helium.

Because hydrogen change into helium.

Due to nuclear fusion reaction hydrogen (proton) converts into helium.

Viren said: (Mar 30, 2016)  
Hydrogen is not capable for this because we get H in the form of He.

What is chromosphere?

Yassine said: (Oct 12, 2016)  
Chromosphere is the second layer of the sun (out of 3).

FYI Helium comes from Helios which is the Greek word for "sun".

He gas is formed due to nuclear fusion of hydrogen atoms around sun atmosphere and the sun is wholly made of hydrogen, which is the source of fuel for the sun.

Because sun is a gas of hydrogen and hellium.

Please explain the answer.
