Answer

Answer:

B. a cloud of gas and dust in space

Brief Explanations:

A nebula is an interstellar cloud made of gas and dust. It is not the core of a massive star (which could become a neutron - star or black - hole), not just a swirling disk with gravity (like an accretion disk), and not specifically the debris from a supernova (though supernovae can create some nebulae).
