Final answer:
The main-sequence star will change the least 10 billion years from now.
Step-by-step explanation:
Out of the given options, the star that will change the least 10 billion years from now is the Main-sequence star. Main-sequence stars like our Sun are still in the middle of their life cycle, where they burn hydrogen in their cores and remain stable for billions of years. On the other hand, red giant stars expand and shed their outer layers, white dwarf stars cool down and fade away over time, and neutron stars can undergo significant changes due to gravitational collapse or fusion processes. Therefore, the main-sequence star is the most stable and unchanged option in the long run.
