Some Basic Concepts of Chemistry

Given below are two statements: one is labelled as Assertion $$\mathbf{A}$$ and the other is labelled as Reason $$\mathbf{R}$$ Assertion A : $$3.1500 \mathrm{~g}$$ of hydrated oxalic acid dissolved in water to make $$250.0 \mathrm{~mL}$$ solution will result in $$0.1 \mathrm{~M}$$ oxalic acid solution. Reason $$\mathbf{R}$$ : Molar mass of hydrated oxalic acid is $$126 \mathrm{~g} \mathrm{~mol}^{-1}$$ In the light of the above statements, choose the correct answer from the options given below.
