Solution

The correct option is B
Sodium hexametaphosphate

Although the name 'Calgon' has been a constant over the years, its composition has been varying. In its original form, when it was introduced, Calgon comprised of $(N a P O_{3})_{6}$ or $N a_{2} [N a_{4} (P O_{3})_{6}]$ . This is known as Sodium hexametaphosphate. It is the hexamer of $N a P O_{3}$ .

Commercially, Sodium Hexametaphosphate is a mixture of polymeric metaphosphates only one of which is $(N a P O_{3})_{6}$
