$\text{KMnO}_4$ acts as an oxidising agent. Its reaction with $\text{Fe}^{2+}$ is represented by the ionic equation below. $\ldots X\ldots \text{MnO}_4^- + \ldots \text{Fe}^{2+} + \ldots \text{H}^+ \rightarrow \ldots \text{Mn}^{2+} + \ldots Y\ldots \text{Fe}^{3+} + \ldots \text{H}_2\text{O}$ When the equation is balanced, what are $X$ and $Y$?
- A$X = 1,\; Y = 1$
- B$X = 1,\; Y = 3$
- C$X = 1,\; Y = 5$
- D$X = 5,\; Y = 1$
