The most massive star known in the universe is thought to be r136a1, which may be as much as 256 times the mass of our sun. what do r136a1 and our sun have in common?
a. they have the same amount of helium.
b. they have the same amount of hydrogen.
c. energy moves slowly through their layers.
d. nuclear fission reactions power them.

C. Energy moves slowly through their layers.

Explanation:

All stars are made of dust and gases. Star is majorly composed of Hydrogen and Helium. Nuclear fusion reaction of Hydrogen atoms powers the stars. All the stars do not have same amount of Hydrogen or Helium.

The energy produced during the nuclear fusion reaction in the core of every star moves slowly through their layers. The energy moves forward in all the directions. Thus, the massive star R136a1 and our star have in common is that the energy moves slowly through the layers.

the answer is C because the stars have layers, for the energy to escape and to be released it goes through the layers.
