Answer 1

The correct option is D, test of independence only

This test is applied if you have two categorical variables and the all sample data is displayed in contengency table and expected frequency for each cell at least 5. This test is used to determine if there is the significant relationship between two categorical variables.

So the term contingency table goes with a tests of independence test.

The goodness of fit test is not goes with contengency table. because for goodness of fit test goes with two columns one is observed frequency and expected frequency. This test is used to test whether the observed sample frequencies differ the expected frequencies.
