Nebula --> Protostar --> Supergiant --> Supernova --> neutron star are the right place of a high-mass star's life cycle in the correct order, from a star's birth to its death.
<h3>What is Protostar ?</h3>
Due to its growing gravity, the protostar will keep condensing. As the hydrogen atoms begin to collide, nuclear fusion will be triggered by the pressure and temperature. The start will then enter its primary sequence, when the inward and outward forces of nuclear fusion are balanced.
Thus, the words are arranged in above statement.
