A stanza in a poem typically has:
A) A central idea - Each stanza often focuses on a specific theme or idea that contributes to the overall message of the poem.
B) A title - While stanzas themselves do not have titles, the poem as a whole may have a title, and individual stanzas can sometimes be referred to as sections.
C) The same number of lines - Stanzas do not necessarily have to have the same number of lines; they can vary in length.
D) The same rhyme scheme - Stanzas may or may not follow the same rhyme scheme, depending on the poem's structure.
So, the best answer would be A) A central idea.
