The mirror changes into a river, to suggest that life flows a lake, to suggest deeper meaning a woman, to suggest personification a magician, to show that life depends on how you look at it

The correct answer is B. a lake, to suggest deeper meaning. The mirror as such is a metaphor of feminine frailty and insecurity; however, when it turns into a lake, it transcends that meaning and evolves into a metaphor of aging, time and change. It doesn't turn into a woman; it just shows the woman's transformation from a young girl into an old woman.
