Match the entries of column I with appropriate entries of column II and choose the correct option out of the four options given.

A-s, B-p, C-q, D-r

5% H₂SO₄ solution means 5 g H₂SO₄ in 100 g of solution, i.e., solvent (H₂O) = 95 g = 0.095 kg

As d = 1.01 g mL^-1, volume of 100 g solution = \(\frac{100}{1.01}\) = 99 mL = 0.099 L

$Molarity = \frac{\frac{5}{98}}{0.099} = 0.515 M$

$Molality = \frac{\frac{5}{98}}{0.095} = 0.537 m$

$Mole fraction = \frac{\frac{5}{98}}{\frac{5}{98} + \frac{95}{18}} = \frac{0.051}{0.051+5.278} = 0.0096$

$Mass fraction = \frac{5}{100} = 0.05$
