@govind...if we dont cram the ans....and think logically..it should be a calcium compound naa ????becoz teeth contain calcium and toothpaste is supposed to strengthen them

The bitter fact in chem is that u may not get the answer by applying logic..especially in inorganic chem...if u know a particular thing then it's fine..otherwise it's better to leave the question...
