Assertion $A:$ $3.1500\,g$ of hydrated oxalic acid dissolved in water to make $250.0\,mL$ solution will result in $0.1\,M$ oxalic acid solution.
Reason $R:$ Molar mass of hydrated oxalic acid is $126\,g\,mol ^{-1}$.
In the light of the above statements, chose the correct answer from the options given below:
$Compound\xrightarrow{{KMn{O_4}/{H^ \oplus }}}$
| $A/mol\,L^{-1}$ | $0.2$ | $0.2$ | $0.4$ |
| $B/mol\,L^{-1}$ | $0.3$ | $0.1$ | $0.05$ |
| $r_0/mol^{-1}s^{-1}$ | $5.0\times 10^{-5}$ | $5.0\times 10^{-5}$ | $1.4\times 10^{-4}$ |
