Flouride amount in water should be.. 1-2 mg/liter

Flouride amount in water should be:
A- 0.2-0.5 mg/liter
B- 1-5 mg/liter
C- 1-2 mg/liter. ***
D- 0.1- 0.2 mg/liter

None of the options you provided are exactly within the optimal range for fluoride concentration in drinking water for preventing tooth decay.
Here's a breakdown:

Optimal range:

According to the United States Department of Health and Human Services and the World Health Organization, the optimal fluoride concentration in drinking water for preventing tooth decay is 0.7 mg/liter. This range can vary slightly depending on factors like climate, local environment, and other sources of fluoride intake.

Your options:

A (0.2-0.5 mg/liter): This range is below the optimal level and may not provide enough fluoride for effective caries prevention.

B (1-5 mg/liter):

This range is too high and can lead to dental fluorosis, a condition that causes white spots or brown streaks on the teeth.

C (1-2 mg/liter):

While this range includes the optimal level (0.7 mg/liter), it also extends above it, potentially increasing the risk of dental fluorosis.

D (0.1-0.2 mg/liter):

Similar to option A, this range is too low for optimal caries prevention.
Therefore, the recommended fluoride concentration in drinking water should ideally be around 0.7 mg/liter, with a slight acceptable range of potentially 0.6 mg/liter to 0.8 mg/liter.

It's important to remember that the ideal fluoride level can vary depending on individual circumstances and local factors. Consult your dentist or healthcare provider for specific recommendations based on your situation.
