1 g of a non-volatile non-electrolyte solute is dissolved in 100 g of two different solvents A and B whose ebullioscopic constants are in the ratio of $1 : 5$. The ratio of the elevation in their boiling points, $\frac { \Delta \mathrm { T } _ { \mathrm { b } } \mathrm { A } } { \Delta \mathrm { T } _ { \mathrm { b } } \mathrm { B } }$, is: (assuming they have the same molar mass)\\
(1) $10 : 1$\\
(2) $1 : 5$\\
(3) $1 : 0.2$\\
(4) $5 : 1$
