Good morning! <3
Okay so when we look at the question it is asking what Whitman and Dickinson had in common, And Walt (Whitman's first name) Had a lot of things in common with Emily (Dickson's first name). They both seemed to focus on the same themes and characteristics in writing as each-other.
Your answer would come down to D. They both challenged the status quo of poetic expression.
