Note : In the following questions a statement of assertion $(A)$ followed by a statement of reason $(R)$ is given. Choose the correct option out of the choices given below each question.
Assertion $(A)$ : In the reaction between potassium permanganate and potassium iodide, permanganate ions act as oxidising agent.
Reason $(R)$ : Oxidation state of manganese changes from $+2$ to $+7$ during the reaction.
  • A
    Both $A $ and $R$ are true and $R$ is the correct explanation of $A.$
  • B
    Both $A$ and $R$ are true but $R$ is not the correct explanation of $A.$
  • ✓
    $A$ is true but $R $ is false.
  • D
    Both $A$ and $R$ are false.
✓

Answer

Correct option: C.
$A$ is true but $R $ is false.
As permanganate ion changes to $\mathrm{MnO}_2$.
