Which of the following statements regarding the evolution of galaxies is true?

(a)   Galaxies do not evolve from one type (e.g. spiral) to another (e.g. elliptical) but interactions between galaxies can change their structure and appearance.
(b)   Once formed, galaxies do not change their nature but slowly age and never interact with one another because they are widely spread in space and are separated by huge voids.
(c)   Galaxies evolve from spiral to elliptical as the arms spiral inwards because of the motions of individual stars.
