    First try balancing the equation

    We'll delete one option first i.e SbH3

    yes that is clear . wouldnt that be the oxidizing agent

    But there is no SbH3 there in the qn right?

    what is the oxidizing agent in this equation

    reducing agent is substance which get oxidized itself by giving electron

    so Mn02 is the answer

    ok so this is simple. Keep this in mind Reduction means there will be a decrease in the product from the reactant Oxidation means there will be an increase in the product

    So as far as the qustion is concerned, Mno4 gets reduced to MNO2 and Sbh2 to Sb. So both Sb and O2 get reduced. Since the options given to you do not have O2, go for Sb

    and that makes the oxidizing agent to be mn04-

    vice versa of agents Oxidising agent Decreases and Reducing agent increases

    so its MnO4

    You need not learn any definition byheart, just understand these simple procedures that i tell you

    So i said Oxidising agent means there will be a decrease in the product Reducing agent means there will be an increase in the product

    check this example out. This equation is self balanced so you need not worry about balancing it

    So try using my method and find out the Oxidising agent and Reducing agent
