Question

question 7
stars are born in
o reflection nebulae
dense cores in a giant molecular cloud
in cookie dough
the local bubble
o all of the giant molecular cloud

Explanation:

Stars form in dense regions of gas and dust within Giant Molecular Clouds. These dense cores collapse under gravity, leading to star formation. Reflection nebulae are clouds of dust reflecting starlight, not sites of star birth. The local bubble is a cavity in the interstellar medium. "In cookie dough" is a non - scientific option. And it's not the entire Giant Molecular Cloud but the dense cores within it where stars are born.

Answer:

dense cores in a Giant Molecular cloud
