The correct sequence in the life cycle of a massive star is:
nebula, protostar, star, super red giant, supernova, neutron star
This sequence outlines the general stages that a massive star goes through during its lifecycle, culminating in a supernova explosion, which can leave behind a neutron star or a black hole, depending on the mass of the original star.
The other options presented do not follow the correct chronological order of stellar evolution for a massive star.
