What is the effect of enjambment in this excerpt from "Porphyria's Lover" by Robert Browning?
That moment she was mine, mine, fair,
Perfectly pure and good: I found
A thing to do, and all her hair
In one long yellow string I wound
Three times her little throat around,
And strangled her. No pain felt she;
A. It conveys pain.
B. It enhances the shocking effect.
C. It introduces a pause.
