Shakespeare is the answer
The correct alternative is "B. The separate stanzas force readers to stop and read each word carefully, which reflects the theme that all elements must be considered individually to appreciate their true value."
This choice turns this considerably simple poem into a more meaningful and turn the words into well-expressed feelings.
Macbeth and his wife had a nice relationship until he encountered the witches who prophesied his kingship. His wife then urged him to kill King Duncan so she would be queen and he king. This of course was desfavorable for both of them. The relationship they have after becoming king and queen is less warm and emotionally penetrating. Macbeth became an old shell of a man (sociopath) while his wife became a lunatic. Things between them wasn’t as they used to be when they had a less social standing.

[She] had kindled the callow fancy of the most idle and shiftless of all
the village lads, and had conceived for this Howard Carpenter one of
those absurd and extravagant passions which a handsome country boy of
twenty one sometimes inspires in a plain, angular, spectacled woman of
thirty. (Willa Cather, "A Wagner Matinee")
