Question
Use the diagram to answer the question.
The life trajectory of a stellar nebula is shown. The stellar nebula, a purple gas ball turns into an average star, depicted as a yellow circle, within 500 million years. The average star turns into a red giant, depicted as a medium sized red circle, within 10000 million years. The red giant turns into a planetary nebula, a bright star surrounded by green and blue gases, within 1000 million years. And the planetary nebula gradually cools into a white dwarf, depicted as a small white circle. The stellar nebula can also turn into a massive star, depicted as a medium blue circle, within 0.1 million years. The massive star turns into a red supergiant, depicted as a large orange circle, within 15 million years. The red supergiant turns into a supernova, a bright white star, within 1 million years. The supernova can either turn into a neutron star, depicted as a yellow sphere with white rays coming out of its sides, or a black hole, a small black circle surrounded by purple rays.
Which of these can a star become at the end of its evolution? Choose the three correct answers.
