Show answer and explanation

Correct answer: (A) J–ii, K–i, L–iv, M–iii

Explanation

Dalton’s law sums partial gas pressures; Fick’s law describes diffusion; Henry’s law gives gas–liquid equilibrium partitioning used in phase transfer; Stokes’ drag law gives small-particle settling in the viscous regime. Thus **J–ii, K–i, L–iv, M–iii;A**.
