I in Order to Visualize the Form of the Regression

i. In order to visualize the form of the regression equation, we can draw a scatter diagram. ii. When a regression line has a zero slope, indicating a lack of a relationship, the line is vertical to the x-axis.
iii. In regression analysis, the predicted value of Y' rarely agrees exactly with the actual Y value, i.e., we expect some prediction error.

A) (i) , (ii) , and (iii) are all correct statements.
B) (i) and (ii) are correct statements but not (iii) .
C) (i) and (iii) are correct statements but not (ii) .
D) (ii) and (iii) are correct statements but not (i) .
E) (i) , (ii) , and (iii) are all false statements.
