Answer:
A) They increase
Step-by-step explanation:
Usually, the solubility of a substance in water increases as the temperature increases.
The solubility curves below show that both NaCl and NaClO₃ follow this pattern.
Between 0 °C and 100 °C, the solubility of NaCl increases by more than 250 %, but the that of NaCl increases by less than 10 %
However, the solubilities of both solutes increase with temperature.
