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

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

**nebula, protostar, star, super red giant, supernova, neutron star (or black hole)**

Massive stars form from nebulae, evolve into protostars, then become main sequence stars. As they exhaust nuclear fuel, they expand into super red giants, eventually ending their lives in supernova explosions. Depending on their mass, they can leave behind either neutron stars or black holes.

Among the sequences listed, the last one fits this progression correctly:

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