Sonnet is a one-sided, 14-line poem. The sonnet word is derived from the Italian word "sonetto", which means "a bit of a sound or a song". Sonnet uses one of several rhyme schemes and holds specific thematic organizations. There are two basic forms of sonnets from which all the others are formed: Petrarchan and Shakespearean.
One of the forms is the sonnet crown, a series of sonnets bound by repeating the last line of a sonnet in the first line of the next, closing, thus, a circle, using the first line of the first sonnet as the last line of the last sonnet.
Correct answer is B. Repetition of the same six words at the ends of the lines
