How is the molar concentration of solute in stationary phase related t

1.	How is the molar concentration of solute in stationary phase related to molar concentration of solute in the mobile phase?(a) Directly proportional(b) Inversely proportional(c) Equal(d) Not relatedThis question was posed to me in an online quiz.My doubt stems from Chromatographic Behaviour of Solutes in chapter Chromatography of Analytical Instrumentation
Answer» Right answer is (a) Directly proportional The EXPLANATION is: In chromatography, molar concentration of solute in STATIONARY phase is directly proportional to molar concentration of solute in mobile phase. Cs α CM Cs = k Cm ‘k’ is the distribution constant.
