Step 1

The Chi-square test can be used for checking the association between categorical variables. The test can be used to decide whether the effect of one categorical data is dependent on the other variable or not on the basis of the critical value and p-value. The expected frequency of each categorical variable is calculated to computed the test statistic.

Step 2

So, the chi-square test tells us which categories of one variable are associated with which categories of the other variable. Therefore, the option (d) is considered correct here.
