Final answer:
The correct sentence is: 'In “The Rime of the Ancient Mariner,” the albatross was initially an omen of good luck.' In this sentence, 'of' is correctly written in lowercase. This follows the rule that prepositions within titles should be in lowercase, except when they start or end the title.
Step-by-step explanation:
The sentence with correct capitalization is: In “The Rime of the Ancient Mariner,” the albatross was initially an omen of good luck. According to the rules of capitalization for titles in English, prepositions such as 'of' should be in lowercase when they are part of a title, unless they are the first or last word. The correct sentence uses this rule accurately.
Capitalization in poetry can often be tied to emphasizing particular words or ideas. For instance, poets like Wordsworth capitalize words like 'Nature' and 'Sea' to personify them or to elevate their importance within the context of the poem. Other capitalized words in poetry could suggest thematic connections, divine or powerful entities, or simply draw attention to those elements.
Consistent with conventions for written works, titles are often italicized or underlined to differentiate them from the rest of the text, but this does not impact the rules of capitalization.
