Question

which object is created during the formation of a star?
a nebula
a protostar
a supergiant
a supernova

Explanation:

• A nebula is a cloud of gas and dust in space, which is the starting material for star formation, not created during the formation process.
• A protostar is formed when a collapsing cloud of gas and dust (from a nebula) begins to heat up and rotate as it evolves towards becoming a full - fledged star.
• A supergiant is a very large star that is in a late stage of its life cycle, long after the initial formation stage.
• A supernova is an explosion that occurs at the end of a massive star's life, not during star formation.

Answer:

B. a protostar
