Solution

The correct option is B are moving farther apart from one another
The red shift occurs due to increase due to increase in wavelength that would be due to the increasing distance between two galaxies, Red shift indicate that galaxy are mainly farther apart from one another

I am sorry to ask my question out of syllabus. My question is:

We know that the universe is expanding rapidly. Every star and planet is going away from one another faster than the speed of light! Then why it is said that our Galaxy (Milky way Galaxy) is coming nearer to our neighbour galaxy (Andromeda Galaxy) and after many years, these galaxies will collide with each other?
