According to the Graph, the correlation between temperature and solubility is positive. Thus, the correct option is C.
What is Solubility?
Solubility may be defined as a property of a substance i.e. solute that is easily dissolved in another substance known as a solvent.
The solubility of any substance is directly proportional to the temperature to some extent, but after a threshold solubility does not increase with an increase in temperature.
Therefore, the correct option for this question is C.
