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;


It creates a sorrowful mood.




It conveys pain.




It enhances the shocking effect.




It introduces a pause.
