Hint: An interjection is a word that occurs on its own and expresses a spontaneous reaction or feeling.

Complete step-by-step answer:

From the hint given to us, we know that an interjection is a word that occurs on its own and expresses a spontaneous reaction or feeling. Hence, we can infer that the word should be meaningless in nature as it is spontaneous. However, it should have a context where the word is exclaimed. Such exclamations are followed by the exclamation mark.
Hurrah is a meaningless exclamation that is uttered when someone achieves something. We observe that it matches our description of an interjection and is followed by the exclamation mark too. Hence, option A is possibly the correct answer.
‘I’ is a pronoun used for the first person singular. We observe that it is a meaningful word and is not followed by an exclamation mark. Hence, option B is not the correct answer.
‘For’ is a preposition used to establish a relationship between two nouns. We observe that it is a meaningful word and is not followed by an exclamation mark. Hence, option C is not the correct answer.
The is a definite article placed before a noun. Definite articles are put before a noun that is certain in nature. We observe that it is a meaningful word and is not followed by an exclamation mark. Hence, option D is not the correct answer.

Note: Whenever an exclamation is used in a sentence, the sentence is called as an exclamatory sentence.
