The correct answer is (D).
Lloyd "loves" car rides, so you are looking for a word that shows how he would get in the car if he was excited about the ride.
There are some words you can rule out right away. "Aggravation" would be shown if he did not like car rides so that can be ruled out. "Apathy" means lack of interest so that would not be appropriate either.
"Dedication" and "devotion" are a little trickier because they do convey a positive message. But they don't really show that Lloyd is excited about the car ride. They may imply that Lloyd just does what his owner tells him to do.
"Alacrity" means
cheerful willingness or eagerness. If you knew that vocabulary word, this would be an easy one. If you didn't know what alacrity meant, you may be able to choose it as the right anwer anyway by ruling out the rest of the wrong answers.
