Isotopes have same number of protons. All isotopes of few elements are stable and non-radioactive. Also, all isotopes of few elements are unstable and radioactive. All elements have isotopes.
All isotopes of carbon can form compounds with oxygen.
So, only statements III and IV are correct.

Statements III and IV are correct

Statements II, III and IV are correct

Statements I, II and III are correct

Statements I, III and IV are correct

Isotopes have same number of protons. All isotopes of few elements are stable and non-radioactive. Also, all isotopes of few elements are unstable and radioactive. All elements have isotopes. All isotopes of carbon can form compounds with oxygen. So, only statements III and IV are correct.
