How are magnetic fields thought to affect star formation in molecular clouds?
A) They can help resist gravity, so that more total mass is needed before the cloud can collapse to form stars. B) They accelerate the star formation process. C) They allow small stars to form in isolation within gas clouds. D) There are no magnetic fields in interstellar space, so there is no effect.
