Explanation

Among the highlighted words, all are incorrectly placed. The correct combination of words that should replace each other in order to make the sentence grammatically and contextually correct is A-B & C-D. The word “active” should be replaced with “outlook” and “getting” should be replaced with “embracing” as the given sentence is saying that aging gracefully involves maintaining a positive mindset, remaining physically active, and accepting the natural changes that come with the aging process. So, the correct sentence after rearrangement of words would be, “Aging gracefully is about maintaining a positive outlook (B), staying active (A), and embracing (D) the changes that come with getting (C) older.”
