Answer:
She carried the purse by its strap.
Step-by-step explanation:
Homophones are words that have the same sounds but differ in their meaning and spelling. This means that some words are the same in the way they are pronounced but their similarity ends there and they are totally different in their spelling and meaning.
In the given sentence, that particular word is "its/it's". Here, the difference lies in the use of the inverted comma, which totally changed everything. "Its" refer to the possessive nature of the noun or pronoun whereas "it's" is the contracted form of 'it is'.
Now, the sentence that uses the correct version of the homophone 'its' is the second sentence.
Here, the 'its' is used to refer to the strap of the purse, which is correct. The 'its' in the other sentences are supposed to be 'it's'.
Thus, the correct answer is "She carried the purse by its strap."
