Step 1

Chi-Square test for independence:

In the test for independence, we test whether there is an association between the categorical variables.

Null hypothesis: There is no association between the two categorical variables.

Alternative hypothesis: There is an association between the two categorical variables.

Step 2

Here, to test the association between categorical variables, the critical region is always located in the upper tail of the distribution.

That is, Option 3 is correct.
