Reviews affect readers by:
It definitely wouldn't be (a) because usually when you are reading a review about something, it is supposed to help give you a clear, big picture of what is going on.
It wouldn't be (b) because reviews usually don't reduce the quality of a work, it usually makes the piece of work seem a lot better.
It wouldn't be (c) because it doesn't look down on a piece of work, especially about its' context. Reviews usually say good things about something.
That leaves you with (d), giving them a new way to look at a creative work. It shows you someone else's point of view on something, making you look at the piece of work at a different angle, and at a totally different light.
You're answer is d) Giving them a new way to look at a creative work.
