Final answer:
Excerpt b) best illustrates Louise Mallard's transformation in 'The Story of an Hour,' as it reflects her shift from grief to an understanding of her newfound freedom.
Step-by-step explanation:
The character of Louise Mallard in Kate Chopin's 'The Story of an Hour' is a dynamic character who experiences a profound transformation after learning of her husband's death. To highlight this transformation, the correct excerpt that showcases Louise's change is: b) "A clear and exalted perception enabled her to dismiss the notion that she would weep again when she saw the kind, tender hands folded in death." This shows Louise moving past her initial grief to a realization of the freedom and opportunities that lie ahead without her husband, thus illustrating her growth and change as a character.
