Official Explanation
The scale on the graph's vertical axis represents effectiveness, defined as the fraction of respondents who considered a given treatment effective, with greater fractions higher on the axis. Therefore, dots higher in the graph represent more effective treatments. The scale on the horizontal axis represents the fraction of respondents who have tried a given treatment, with greater fractions farther to the right. Therefore, dots farther to the right in the graph represent treatments that more people have tried. The dot representing exercise is both the highest and the farthest to the right, indicating that exercise is both the most effective treatment and the one the most people have tried.
The correct answer is exercise.
As discussed in the analysis above, dots higher in the graph represent more effective treatments, and dots farther to the right represent treatments that more people have tried. The treatments that more than half the respondents have tried are those represented by dots to the right of the mark at 0.5 on the horizontal axis. Among those dots, the one labeled "caffeine" is lowest, indicating that caffeine is the least effective treatment that more than half the respondents have tried.
The correct answer is caffeine.

1)C,exercise since it is at the topmost section of graph in terms of the vertical axis (effectiveness fraction) and in the rightmost side in terms of horizontal axis.(fraction who tried the option)
2) Caffeine,since it is >0.5 at the horizontal axis
