Explanation:I’m not 100% sure how to explain it but I’m almost for sure it’s d.
What is the exoeruent. Searched it up on google and only came up with two search results. None related to chemistry
After finding the oxidation states of atoms, you identify the half reactions (option c).
The half reactions are given by the change of the oxidation states of the atoms.
For example if Cu is in the left side with oxidation state 0 and in the other side with oxidation state 2+, then there you have a half reaction (oxidation reaction). And if you have O with oxidation state 0 in the left side and with oxidation state 2- in the right side, there you have other half reaction (reducing reaction).
