C) It makes nature seem invested in humanity, as opposed to being indifferent and random, which the speaker fears more than anything
Explanation:
By personifying an element in nature and putting it in the context of innocent love of a child Edgar Allan Poe delves into the Romantic idea of a child being connected to nature through his innocence and thus comes his ability to find amorous love for an element. The transference of love cliches on the dynamic accentuates this.
Ultimately, the poem is about the synergy of humans with nature that only children can understand and not the adults, and the dejected and desperate tone of the poem suggests the same: being afraid of losing this connection.
