The outcomes from a chromatogram are displayed. Distances covered: Solvent: $5.0\,\text{cm}$ Substance X: $3.0\,\text{cm}$ Substance Y: $2.5\,\text{cm}$ Which row shows the $R_f$ values for substance X and substance Y?
- A$R_f(X)=0.5,\; R_f(Y)=0.6$
- B$R_f(X)=0.6,\; R_f(Y)=0.5$
- C$R_f(X)=1.6,\; R_f(Y)=2.0$
- D$R_f(X)=2.0,\; R_f(Y)=1.6$
