Respuesta :

 A star by the burning of hydrogen into helium can only go so far into making the heavier elements. It takes a supernova explosion to make the really heavy elements. These are blown out into space where new stars may form and use these heavier elements, like our sun and earth.

A big star expands into a supernova when heavier components are generated through fusion. So, "supernova" is the correct answer.

What does a massive star expand into?

Carbon fusion products can be further processed to produce;

  • Silicon
  • Sulfur
  • Calcium
  • Argon

These elements can also combine to form iron when heated to an even higher temperature. Massive stars move through these phases at breakneck speed and expand into a supernova.
