Where are stars born?
A)reflection nebulae
B)dense molecular clouds
C)HII regions
D)the intercloud medium

Question

Quizplus · Accepted Answer

Stars are born from the gravitational collapse of dense molecular clouds. These clouds have a high enough density and low enough temperature for gravity to overcome thermal pressure and pull the gas and dust together into a protostar. Other options mentioned, such as reflection nebulae and HII regions, can be sites of star formation but are not the primary location. The intercloud medium is not dense enough to trigger gravitational collapse.
