The correct option is C Hurrah
An interjection is an exclamation or an abrupt remark.
It's a word or two (usually followed by an exclamation mark), that expresses a sudden emotion. It is not grammatically
connected to the rest of the sentence.
Option B: In the given sentence, 'Hurrah' is an interjection as it's an exclamation that expresses a sudden joy or happiness. Also, it is followed by the exclamation mark '!' Hence, option B is correct.
Option A: 'The is an article, it's function is to modify the noun, 'game'. It does not express any sudden emotion.
Option C: 'We' is the subject of the verb 'won'. It is a pronoun, not an exclamation.
Option D: 'Game' is the object of the verb 'won'. The object, too, isn't an exclamation.
Hence options A, C, and D are incorrect.
