read the excerpt.

from “my last duchess” by robert browning . . oh sir, she smiled, no doubt, whene’er i passed her; but who passed without much the same smile? this grew; i gave commands; then all smiles stopped together.
what has happened to the duchess?

the speaker has had her killed.

the speaker has forced her to obey him.

she has grown to hate her husband.

she has become sad and withdrawn.
