C: 35-55
D: 10.0 -11.0

The answer is: B

Explanation

The correct answer is (B) 6.5 - 8.0.

The pH value of potable water, which is safe and suitable for drinking, typically falls within the range of 6.5 to 8.0. This range is considered neutral to slightly alkaline and is generally recommended for maintaining the quality and taste of drinking water. pH values below 6.5 can indicate acidity in water, while values above 8.0 can indicate alkalinity. It is important to note that specific regulations and standards may vary between countries or regions, so it is advisable to refer to local guidelines for precise pH requirements of potable water.
