Solution

The correct option is E E
The graph E shows the best relationship of the number of grams of a solid that are soluble in 100 grams of $H_{2} O$ at varying temperature if the solubility begins at a small quantity and increases at a slow, steady pace as the temperature is increased. The graph is a straight line with positive slope making positive y intercept.
