Explanation:
The regression line of y on x is derived by the minimization of vertical distances in the scatter diagram.

Regression analysis is a statistical method used to examine the relationship between two or more variables. The regression line is a line that best fits the data points in a scatter plot. It is used to predict the value of one variable based on the value of another variable.

The regression line of y on x is derived by the method of least squares. This method minimizes the sum of the squared vertical distances between the data points and the regression line. The vertical distance is the distance between the observed value of y and the predicted value of y on the regression line.

Therefore, the correct answer is option A, i.e., the minimization of vertical distances in the scatter diagram. Horizontal distances have no role in the derivation of the regression line of y on x.
