The answer will be (b) Potassium is oxidised and Magnesium is reduced.
As oxidation state of magnesium in the reactant side is +2 and in the product side it is 0 so form this we can conlude that magnesium is reduced.
Oxidation state of potassium in the reactant side is 0 as it exist in solid form and the oxidation state in the product side is +1 which is in aqueous state. From here we can conclude that potassium is getting oxidised in the reaction as it oxidation state is increased.
