Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Answer is (C). Ni(CO)4 has both electrovalent or Ionic bond & Covalent bond as well. (CO) has covalent bond with triple bond between them & a lone of electron on both C & O. Whereas the whole compound overall is Ionic in nature with formal charge on CO = 0.

In Na2SO4, sodium acts as the cation with the sulphate anion which means that they share an ionic bond, while the sulphur and oxygen atoms in sulphate are covalently bonded.
Sir Ni(CO)4 contains covalent C=O and ionic bond with Ni4+, so why it will not be answer?
Ni is neutral here.. and the bond between Ni and CO is co-ordinate.
