Which is a possible sequence in the life cycle of a massive star? (1 point)

Question

• planetary nebula, super red giant, protostar, supemova, star, black hole
• supernova, star, black hole, planetary neoula, super red giant, protostar
• nebula, protostar, star, super red giant, supernova, neutron star
• super red giant, protostar, nebula, star, neutron star, supernova

Answer 1

The correct possible sequence in the life cycle of a massive star is:

nebula, protostar, star, super red giant, supernova, neutron star.

In this sequence:

1. A nebula (cloud of gas and dust) collapses under its gravity to form a protostar.
2. The protostar becomes a main sequence star.
3. The star evolves into a super red giant.
4. The super red giant undergoes a supernova explosion.
5. Depending on the mass, the remnant can either become a neutron star or a black hole.

This sequence accurately represents the life cycle of a massive star.
