Answer:
B. First and second lines rhyme ; third and fourth rhyme
Step-by-step explanation:
The rhyme patter of a stanza or poem is how the last syllables of each verse rhyme with the other verses in the stanza, as you can read in the stanza there is a AABB rhyme scheme:
Laugh and be merry, remember, better the world with a song,
Better the world with a blow in the teeth of a wrong.
Laugh, for the time is brief, a thread the length of a span.
Laugh and be proud to belong to the old proud pageant of man.
As song and wrong rhyme that is a rhyme in the first and second line, and there is a rhyme with span and man in the third and fourth line of the stanza., that´s why the correct answer would be B.
