• D. Haiku is a Japanese poetic art form and many poets enjoy the challenge of writing a poem within its rules

Answer 1

The correct option is A Although the format remained unknown to Americans until the $1950s$ haiku dates back as early as the seventh century

The haiku is as popular as it is difficult to master. Composed of only three lines and 1717 or fewer syllables, haiku have been written by some of the world's most prominent poets.So before this line Option A should be inserted because this passage is all about Haiku.

The other options will not work because other options are like not introductory lines.

Hence option A is correct.
