The correct answer is A. A haiku presents a single moment through its brief structure.
Explanation:
The Japanese haiku is a type of short poem that includes only three verses and seventeen syllables, due to the structure of these poems they focus only on one particular moment, season, feeling, etc. Additionally, in haikus, there is no rhyme but only a precise structure of 5 syllables in the first and third line and 7 in the second line. On the other hand, English romantic poems focus on strong feelings or emotions, nature or the individual that is developed in one or multiple stanzas that can include different themes, besides this in romantic poems it is possible to find rhyme and a fixed structure.
According to this, one of the main features that make haiku different from English romantic poems is that "A haiku presents a single moment through its brief structure" because a romantic poem can present multiple details related to different moments, events, feelings, etc.
