Right choice is (a) True

The explanation: For drinking purposes, water should be tested for fluoride ion concentrations. Its deficiency in drinking water is harmful to man and causes diseases such as tooth decay. But, if present in higher concentrations, it causes brown mottling of teeth. It can also lead to harmful effects in bones.
