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.

Based on the provided information about the life trajectory of stellar nebulae and the evolution of average and massive stars, the correct responses are:
B) Average stars evolve more slowly than massive stars.
D) Massive stars evolve more quickly than average stars.
Massive stars have a much faster evolutionary process compared to average stars, as indicated by the time frames given for each stage of their evolution.
Thank you for the clarification! Based on the provided information, the correct statements about stellar evolution are:
B) Average stars evolve more slowly than massive stars.
E) Massive stars evolve more quickly than average stars.
These choices reflect that massive stars undergo their evolutionary stages much more rapidly compared to average stars.
