The sentence which most effectively helps readers envision a scene is "there is a low murmur of voices throughout the play as women shoulder..." (option C)
To envision means to see or to visualize something. Authors provide certain details to help us see the scenes, especially sensory details, that is, information appealing to our senses.
Thus, authors provide information about how the characters move, what they wear, the sounds they make, and so on.
