How do dying stars contribute to the formation of planets? a. they emit helium gas that attaches to nearby planets. b. they remove low-mass elements from the planets’ crust. c. they cause nuclear fusion inside the inner core of planets. d. they produce heavy elements such as iron and gold.

Science says that dead stars become neutrons when they die. Neutron stars are characterized by having a small radius with a high density. Protons and electrons are compressed in a very tight space making it highly dense. As it gets more compresses, it causes implosion in the form of shockwaves called supernova.

Thus, the answer is C.

Stars with about eight to 20 solar masses become neutron stars when they die. When infalling matter from the imploding star's outer layers reaches this neutron core, it bounces back and generates a powerful shockwave that blasts away the star's outer mantle in a stellar explosion called a supernova.

The answer is C, They cause nuclear fusion inside the inner core of planets.
