Where is the poet? Post the poet then I can answer it.
Answer: B is the answer
Explanation: the sentence is in the past so you have to put had it's kinda hard to explain
The correct answer is A.
The sentence should be written like this: <span>Sadly, even after that water is found, only some of it's clean and safe enough to drink.

</span>
