Answer

H Explanation 1. Interpret Experiment 2 trend In Experiment 2, pH increasing causes higher cadmium percent recovery until it reaches a peak, then levels or drops slightly. 2. Locate pH range for 7.5 Based on data pattern, pH 7.0 and 8.0 give recoveries around 88–95%. pH 7.5 is between those, so expected ~90%. 3. Choose matching option ~90% lies between 88% and 95%, which corresponds to option H.
