The first scatter plot does not have a zero correlation.
Option(a) is correct.
A statistic called correlation gauges how much two variables change in connection to one another.
Correlation quantifies correlation but cannot determine whether x causes y or vice versa, or whether a third component is responsible for the association.
A scatterplot may make it easier to spot correlation, particularly when the variables have a non-linear but nevertheless significant association.
Zero means there is no correlation between the two variables under comparison.
A 0 correlation indicates that there is no relationship between the two variables according to the correlation statistic. This merely indicates that there isn't a linear relationship, not that there isn't any link at all. The first scatter plot does not represent a linear relationship, thus, it has zero correlation.
