Answer:option D= 82.6°C 
Explanation:
Step 1: determine the molality
Molality = moles of solute/ kg of solvent. 
(Recall: number of moles= mass / molar mass).
Therefore, 375/256.5 g/mol = 1.4620 mole.
Substituting into the molality equation we have, 
1.4620/ 0.1250kg = 11.696.
∆T(b) = k(b) × molality
∆T(b) = 82.6°C
