Answer 1

The correct answer is C. main sequence star late in its life.

A planetary nebula is formed when a low to intermediate mass star (like our Sun) expands and sheds its outer layers after exhausting its nuclear fuel. This phase occurs after the star has gone through its red giant stage and is not related to planets or neutron stars.
