Question

a low mass star will eventually turn into a
supernova
black hole
black dwarf
protostar

Explanation:

Low - mass stars like our Sun, after exhausting their nuclear fuel and going through the red - giant phase and shedding their outer layers to form a planetary nebula, leave behind a white dwarf. Over an extremely long time, this white dwarf cools down to become a black dwarf. Supernovas and black holes are formed from high - mass stars, and a protostar is an early stage in star formation.

Answer:

C. Black Dwarf
