When there is a high positive correlation between two variables, we would expect most of the data points to fall in the upper right and lower left quadrants. This is because both variables will have high values and move together, hence falling in the upper right quadrant. In the lower left quadrant, both variables will have low values and move together due to the negative correlation. Therefore, option B is the best choice.
