Hint: In moderation, fluorine helps preserve the structure of bones and related tissues. A very common element is fluorine. The element behaves in the form of ions of fluoride. Fluorides are abundantly found in the Earth's crust. It is also found in natural water and food sources in abundance. Find an alternative that is similar to that of a bone in the structure.
Complete answer: In the growth of bones, the enamel of the teeth, and thyroid glands, fluorine helps. The way it fights against cavities that contain bacteria or acidity is by mixing the tooth enamel with phosphorus and calcium ions. This will result in fluorapatite, a phosphate compound in the form of a strong crystalline solid, being formed. But this only works in moderation. Natural fluoride bioavailability is found to be about ninety percent. This implies that almost all of the fluoride injected naturally gives the body ample fluorine production. This is where contamination from fluorine comes in. The increase in the amount of fluorine absorbed by the body causes the enamel, known as fluorosis, to deteriorate. The excess fluorine found in the bones and teeth will replace the calcium ions, making them very brittle and susceptible to acid attacks. A rise in the quantity of fluoride intake in children has been shown to have deleterious effects on bones and teeth.
Hence, option B-Teeth is the correct answer.
Note: As an act to enhance dental health, water fluoridation has occurred in many developed nations. Many toothpaste firms nowadays also use fluoride in their products. Water fluoridation is the controlled adaptation of fluoride to reduce the supply of public water.
