Hey there!
Trochaic tetrameter (try saying that five times fast) is a line of a poem that usually contains about eight syllables that goes in the pattern stressed, unstressed, stressed, unstressed, etc.
But, look at the syllable count for each of the answer options!
A: 10 syllables
B: 8 syllables
C. 10 syllables
D. 10 syllables
So, we immediately see that the correct answer is B, and this fits our stressed, unstressed pattern because you say it like PEter PEter PUMPkin EATer. If you try doing this with the other answer options it sounds really stupid, I tried it and it sounds pretty weird XD
Therefore, the answer is B. Peter, Peter, pumpkin eater.
Have a wonderful day!
noun phrase is the answer
Proper nouns? Unless your looking for a more comples answer
A topic is like a title of a book and a Unit is like the chapters in the book.
