Answer
A
He could add another acid to the pool to compete with the existing acid.
B
He could add a metal salt to the pool to precipitate the acid.
C
He could add a base to the pool to neutralize the acid.
Explanation
A base neutralizes an acid, reducing the water’s acidity and raising its pH. The pool owner could add a suitable base to counteract the excess acid. Adding another acid would make the water more acidic, and a metal salt is not the standard way to neutralize the acid.
