Im pretty sure its d because stanzas have to have the same amount of lines and a break is in between stanzas but idk lmk if im wrong
Because of the truth that every argument has a counter argument, the purpose of a counter argument is to give another possible proposal if the reader does not wish to accept your own.
The sentence is using the word "was" instead of the word "were". Using "were" is appropriate for talking about the past tense for plural things. Simply change the words. Hope this helped :))
