The title already gives the reader an idea about the poem's theme and meaning.
C, B, and D are not as clear. These titles make you question what the poems may be about, and they do not effectively summarize the poems. The titles lack elaboration, which makes it difficult to understand the theme of the poem solely through the title. They are single-word titles that could have several different meanings.
