Explanation Let us consider a raisin cake that is baking in an oven. For the raisin which are in the cake can be considered as the reference point. As soon as it bakes in the oven all the other raisin in the cake move away from the raisin that we considered, it is also noticed that the raisin that are at the farthest point moved faster. In a similar way all the galaxies are moving away from us and the galaxies that are farthest are moving faster. Thus we can say that the universe is expanding Hence, the correct option is a...
