Hint:Calgon is a market name. Calgon is a complex compound which has six phosphate ions which forms a ring surrounded by the sodium ions. The chemical name for Calgon is sodium hexametaphosphate.

Complete answer:
Calgon is the trade name for a complex name as sodium hexametaphosphate and the chemical formula of Calgon is ${{(NaP{{O}_{3}})}_{6}}$. Generally, the ring structure in Calgon is formed by the metaphosphate ring. The complex form of Calgon is $N{{a}_{2}}[N{{a}_{4}}{{(P{{O}_{3}})}_{6}}]$ .

Hence, the correct answer is option (A) i.e. the chemical formula of Calgon is ${{(NaP{{O}_{3}})}_{6}}$.

Additional information:
We can also write the formula of a compound by first writing the IUPAC name for that compound. But since Calgon is a complex compound the IUPAC name of Calgon is quite complex.
IUPAC stands for international union for pure and applied chemistry ach the steps to write the IUPAC nomenclature are mentioned below:
Step 1- select the longest carbon chain
Step-2 identify the substituents attached to the parent chain and number the parent chain from the end which gives the lowest number to the substituent

While writing the IUPAC nomenclature the substituents present in the given compound should be arranged in alphabetical order and if the same substituent occurs more than one then the prefix like di, tri, tetra etc. are used. It is important to put a comma between two numbers and a dash between a number and the name of the substituent. While arranging the substituents in alphabetical order we should ignore the prefix like di, tri, and tetra and arrange on the basis of the first letter of the substituent name.
