To delete the node that curr references, we need to set the next pointer of its previous node (prev) to the node that comes after curr (curr.getNext()). Choice D achieves this. The other options either set curr's next pointer to itself (C) or set curr's next pointer to prev (B), which does not achieve the desired result. Choice A sets prev's next pointer to curr, which has the opposite effect of what we want (it would actually insert a node after curr).
