Stronger the oxidizing agent, higher is the:

Explanation

The strength of an oxidizing agent is determined by its ability to accept electrons from other substances, causing them to undergo oxidation. The higher the strength of the oxidizing agent, the more readily it can accept electrons and cause oxidation to occur. Therefore, the answer to your question is: Higher is the oxidizing power or ability to oxidize other substances. In other words, a stronger oxidizing agent has a greater capacity to cause oxidation in other substances. An oxidizing agent oxidizes other species while reducing itself. In other words, it causes others to lose electrons while itself gaining those electrons. A strong oxidizing agent does this relatively easily and the quantitative measure of this ability is expressed using oxidation/reduction potentials. Since a strong oxidizing agent itself gets reduced easily, it will have a high reduction potential. Therefore option C is correct.
