Explanation

Why the other choices are wrong
Choice A
Choice A is incorrect. The sentence identifies both of Hacker’s poems as sestinas; it doesn’t use one of the poems to illustrate the form of a sestina.
Choice C
Choice C is incorrect. While the sentence appears to use the poem "Forage Sestina" to illustrate a feature of the sestina form, it misrepresents the information in the notes. According to the notes, "Forage Sestina" doesn’t use these six end words; it uses six other words instead.
Choice D
Choice D is incorrect. While the sentence uses the poem "Towards Autumn" as an example of one of Hacker’s sestinas, it misrepresents the information in the notes. According to the notes, "Towards Autumn" doesn’t use these six end words; it uses six other words instead.
