Final answer:
The common theme in the excerpts from 'The Jilting of Granny Weatherall' and 'The Love Song of J. Alfred Prufrock' is that personal worth isn't based on how others treat us. Both characters reflect on their pasts and demonstrate a sense of self-worth separate from others' actions. The correct answer is option A.
Step-by-step explanation:
The theme best developed in both excerpts from Katherine Anne Porter's "The Jilting of Granny Weatherall" and T.S. Eliot's "The Love Song of J. Alfred Prufrock" is A. Personal worth isn't derived from how others treat us. Granny Weatherall reflects on being left by her first fiancé but takes pride in the life she built with her husband, who she found to be far better. This shows she does not measure her worth by that rejection. Similarly, Prufrock does not see himself as a hero like Hamlet, but he recognizes his role as necessary and significant.
In "The Love Song of J. Alfred Prufrock", the poem's title suggests a traditional love song, but Eliot flips this expectation by exploring themes of inadequacy and self-doubt, similar to how Renaissance poets used the theme of unrequited love to discuss broader topics.
