The correct answer is A. (9) Sadly, even after that water is found, only some of its clean and safe enough to drink.
Step-by-step explanation:
In grammar, a contraction refers to putting together two or more words usually by omitting certain letters and using an apostrophe (') to indicate the contraction. Additionally, the apostrophe is necessary because without this it cannot be identified two words have been contracted and this leads to changes in the meaning of sentences.
In the case of sentence (9) "Sadly, even after that water is found, only some of its clean and safe enough to drink" this is missing an apostrophe in "its" because in this case, this word refers to "it is" or "it's" that expresses the condition of water as clean and safe rather than to "its" that is used as a possessive form of the noun "it".
