Final answer:
Kepler 186-f is the better option to sustain human life due to its similarities to Earth and its location within the habitable zone.
Explanation:
Out of the options given, I believe that Kepler 186-f is the better option to sustain human life.
Kepler 186-f is an exoplanet that is similar in size and temperature to Earth. It is located within the habitable zone of its star, which means it receives the right amount of heat and light to support liquid water, a key ingredient for life as we know it.
Although Proxima b is also located within the habitable zone of its star, it is subjected to intense stellar flares which could have detrimental effects on the planet's ability to sustain life.
