A) -1.0
B) -0.5
C) 0
D) 1.0

If the points on the scatter plot can be connected by a flat horizontal line, it implies that there is no linear relationship between the X and Y variables. In other words, as X values change, the corresponding Y values do not systematically increase or decrease. Therefore, the correlation coefficient between X and Y would be close to zero (i.e., no correlation). Hence, the closest value to the correlation coefficient would be C) 0.
