Answer 1

The correct answer is - the major difference between the spiral and elliptical galaxies is that elliptical galaxies lack a significant disk component, although both types have the halo component.
The spiral galaxies have the halo component, and also have a bulge and thin disk, while the elliptical galaxies also have the halo component, have bulge but no disk whatsoever.
