Suppose a dense core forms out of an interstellar cloud that is unusual because it does NOT rotate. How might the resulting protostar differ from the majority of other protostars?
A) It would begin fusion at a higher internal temperature.
B) It would most likely lack a protoplanetary disk.
C) It would take much longer to form.
D) It would use a different set of fusion reactions to power itself.

Protostars typically form with rotation, which contributes to the formation of a protoplanetary disk around them due to the conservation of angular momentum. A dense core that does not rotate would likely lead to a protostar without a protoplanetary disk, as there is no angular momentum to spread material into a disk shape.
