Final answer:

Step-by-step explanation:
The interjection in the given sentence is Whoopee!
An interjection is a word or expression that occurs as an utterance on its own and expresses a spontaneous feeling or reaction. It is a diverse category, encompassing many different parts of speech, such as exclamations, curses, greetings, response particles, hesitation markers, and other words.
Interjections are sometimes classified as particles, a catch-all category that includes adverbs and onomatopoeia. The main thing these word types share is that they can occur on their own and do not easily undergo inflection, but they are otherwise divergent in several ways.
An interjection is a word or phrase that is grammatically independent from the words around it, and mainly expresses feeling rather than meaning. Oh, what a beautiful house! Uh-oh, this looks bad. Well, it's time to say good night. Actually, um, it's not my dog.
Interjections are used to express some kind of emotion in a sentence. You can also use them as fillers, and the good part is that they do not possess any grammatical function in the sentence. The word Interjection was created from the Latin word inter (between) and jacĕre (to throw).
