Final Answer :
B
Explanation :
In KClO4, the oxidation number of Cl is +7. This is because K has an oxidation number of +1, and oxygen typically has an oxidation number of -2. In the compound, there are four oxygen atoms, contributing a total of -8. To balance the charges to zero (since the compound is neutral), Cl must have an oxidation number of +7.
