That would be d).

Sulfur has an oxidation state of S2- if seen from the periodic table. It forms Sulfurous acid so, Sulfurous ion is the closest answer compared to all the other options you have!

Hope this helps

Answer 2

The answer is c)copper, Cu*, cuprous ion

Step-by-step explanation:

Copper is the chemical element and one of the transition metals. Its main utility is due to its combination of its chemical, physical, electrical and abundance properties. Copper is obtained from chalcocite, covelite, etc. Copper is the first element of subgroup Ib of the periodic table. Its atom has the electronic structure 1s22s22p63s23p63d104s1. Its low ionization potential of the 4s1 electron results in an easy separation to get copper (I), or cuprous ion, Cu+,
