BThey shine very brightly.
CThey have a triangle shape.
DThey contain iron in their cores.

Verified Answer :

Final answer:

All stars are primarily composed of gases, mainly hydrogen and helium. This gaseous composition is a fundamental property that defines stars and enables nuclear fusion. Other attributes, such as brightness and core elements, can vary among different stars.


Explanation:

One physical property that all stars share is that they are made of gases. Stars primarily consist of hydrogen and helium, along with trace amounts of other elements. This gas composition allows them to undergo nuclear fusion in their cores, which produces the energy that makes them shine.

While many stars do shine very brightly and some can contain iron in their cores, these characteristics can vary from star to star. However, the gaseous nature of stars is a fundamental property that is universally applicable.
