Hope am right and hope this helps

plz give me brainlist :)

Answer 2

Answer:

Type A is a lens galaxy and Type B is an irregular galaxy.

Explanation:

Type A: Lens galaxies' have a large flattened core. lenticular galaxies have a shape reminiscent of a lens (hence the alternative name).

Type B: Irregular galaxies' do not have a regular shape. An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy. Irregular galaxies do not fall into any of the regular classes of the Hubble sequence, and they are often chaotic in appearance, with neither a nuclear bulge nor any trace of spiral arm structure.
