A. KBr is the correct answer

Answer:
Only KBr is the solute that will remain unsaturated at 105 degree Celsius and the rest already gets saturated at lower temperatures such as NaClO3 gets saturated at 80 degree Celsius.
NaCl gets saturated at 90 degree and KNO3 somewhere before 100 degree.
Hence, as a result the only solute left is the KBr which remains unsaturated even at 105 degree.
