Answer:
Answers A and B both prove the point of the question.
It is called Rhyme Scheme ( type: enclose rhyme).
Rhyme is the repetition of sounds in a word used for example at the end of lines of poetry, within a word, in songs, etc.
So as a consequence, Rhyme Scheme is the pattern of rhymes, for example at the end of a poem. They are representing by using letters of the alphabet so that each rhyme in a poem that rhyme with other has assigned a letter (starting with the letter 'A').
Enclose rhyme or enclosing rhyme is the rhyme scheme ABBA. For example:
"Love had us mesmerized under its magic spell A
Our youth's enchanted vision of what life would be B
Innocent intentions that let our lives feel free B
Enraptured in each other's arms as twilight fell." A
The correct answer is "the unstressed-stressed combination mimics waves". Iambic feet is a type of metrics used particularly in traditional English poetry to add an unstressed syllable followed by a stressed syllable. The name iamb comes from this combination of unstressed-stressed, while feet is the name given to a group of syllabes at which the rhythm is measured. In this case Whitman used iambic feet to accomplished the unstressed-stressed effect is his poem.
