Considering mass percentages, stars in the vicinity of the sun contain only 2% other elements by mass. Other than the main components, hydrogen and helium, stars have some heavier elements such as carbon, nitrogen, oxygen and iron. These elements are found near or in the star's core and are ejected into space when the star dies.
Answer:
The correct answer is option E.
Explanation:

Mass of ferric oxide decomposed = 57.0 g
Moles of ferric oxide decomposed = 
According to reaction, 2 moles ferric oxide on combustion gives 824.2 kJ of heat.
Then heat given by on decomposition of 0.35625 mol of ferric oxide will be:

So, on decomposition of 57.0 grams of ferric oxide 147 kilo Joules of heat was released.
