Answer: The correct option is Metal + polyatomic anion.The name will be 'Calcium carbonate'.

Solution:

Salts name is made up two parts:

  1. First part is name of cation here present in salt.
  2. Second part is name of polyatomic anion like :
    Cl^-\text{is chloride},SO_4\text{is sulphate} etc.

So,the name of
CaCO_3 is calcium carbonate.Here,metal ion in the salt is calcium metal and the anion is polyatomic carbonate ion.
