    Given below are two statements: Statement I : Mohr's salt is composed of only three types of ions-ferrous, ammonium and sulphate. Statement II : If the molar conductance at infinite dilution of ferrous, ammonium and sulphate ions are x1,x2x_{1},x_{2} and x3 S cm2 mol−1x_{3}\text{ }S{\text{ }cm}^{2}{\text{ }mol}^{- 1}, respectively then the molar conductance for Mohr's salt solution at infinite dilution would be given by x1+x2+2x3x_{1} + x_{2} + 2x_{3} In the light of the given statements, choose the correct answer from the options given below
