Final Answer:
The possessive noun in the sentence “John’s dog was excited to go to the park” is a) John's
Explanation:
In the given sentence, “John’s” is the possessive noun as it shows ownership or possession.
The apostrophe-s (‘s) indicates that the dog belongs to John. This construction signifies that the dog is owned by John, making “John’s” the possessive noun in the sentence.
The word “dog’s” is a possessive form, but in this context, it functions as an adjective modifying the noun “excited.” Similarly, “park’s” is not a possessive noun but rather a noun followed by an apostrophe-s (‘s), indicating a contraction of “park is.
” Lastly, “excited” is a verb describing the action of the dog and is not a possessive noun.
So correct option is a) John's
