Solution

The correct option is A No/zero correlation
Let's have an example first.

The following scatter plot depicts the data set for monthly income vs. weight of individuals.

Logically, it is very clear that we cannot relate the monthly income of an individual with her body weight.

From the scatter plot, we also observe that there is NO relationship between the independent variable in horizontal axis and dependent variable in vertical axis.

Hence, the scatter plot denotes no or zero correlation, where there is no visible relationship between the two variables.
