how are population ii stars different than the sun, a population i star?
population ii stars are lower in heavy elements (metals) than population i stars.
the sun is a population ii star, thus there is no difference.
all of these
population ii stars are located only in the disk of the galaxy.
the orbits of population ii stars are more circular than population i stars.

Explanation:

Population II stars are older and formed earlier in the universe's history. At that time, there were fewer heavy - elements (metals) available as the universe had not gone through as many stellar nucleosynthesis and supernova events to create and disperse heavy elements. Population I stars like the Sun formed later, incorporating more heavy elements from previous stellar generations.
The Sun is a Population I star, so the option "The sun is a population II star, thus there is no difference" is incorrect. Population II stars are not located only in the disk (they are in the halo as well), and their orbits are more elliptical (not more circular) compared to Population I stars.

Answer:

Population II stars are lower in heavy elements (metals) than population I stars.
