Solution

The correct option is B ${100.25}^{o} C$
Solution of non-electrolyte having same concentration will boil at same same temperature.
$10 g of urea; m = \frac{\frac{1}{60}}{v} = \frac{1}{60 v}$

$3 g of glucose; m = \frac{\frac{3}{180}}{v} = \frac{1}{60 v}$

We know

$Δ T_{b} = k_{b} \times m$

$\Rightarrow Δ T_{b} \propto m$

Here, molarity remains unchanged

Hence, they have the same boiling point.

Hence, the correct option is $B$
