Answer: I think it's Meter
Explanation:
In poetry, a stanza is a division of four or more lines having a fixed length, meter, or rhyming scheme.
Meter is the number and type of rhythmic beats in a line of poetry.
Rhythm is a part of the structure of a poem unless the poem is written in free verse.
Verse refers to a single line, a stanza, or the entire poem itself.
