A 1.25 g Shelcal 500 tablet contains 1250 mg of $$\text{CaCO}_3$$. A student dissolved one tablet in water to make 1.0 L of solution X. 10.0 mL of solution X was titrated with 0.0198 M EDTA and MgEDTA mixture in the burette and found the $$\text{CaCO}_3$$ content matched the label claim, the molar mass of $$\text{CaCO}_3$$ being 100.0 g per mol. The correct option is

A

The burette reading is 6.31 mL and molarity of Shelcal solution is 0.125 M

B

The burette reading is 10.00 mL and molarity of Shelcal solution is 0.0125 M

C

The burette reading is 6.31 mL and molarity of Shelcal solution is 0.0125 M

D

The burette reading is 10.00 mL and molarity of Shelcal solution is 0.125 M
