One possible explanation for a galaxy's type invokes the angular momentum of the protogalactic cloud from which it formed.Suppose a galaxy forms from a protogalactic cloud with a lot of angular momentum.Assuming its type has not changed due to other interactions,we'd expect this galaxy to be
A)an irregular galaxy.
B)an elliptical galaxy.
C)a spiral galaxy.
D)a torn and incoherent galaxy.
