The First one has a sense in poetry but not in the question, so not this one.
The Second one doesn't really have to do with the term enjambed, so not this one either.
The Third one is basically the opposite definition of enjambed, as enjambed means to trick a reader into thinking of an idea then in the next line giving an idea that conflicts it.
The Fourth one has more of a relation to enjambment since it enhances the rhyme by adding confusion to the reader for a calculated term.
So your answer is Enhance a rhyme.
Really hope this helps.
