Answer: B
The non-parametric test is the chi-square test.
A non-parametric test makes no assumption about the shape of the population distribution and can be used with nominal or ordinal data. The chi-square test compares observed with expected frequencies in categories, so it works with counts and needs no assumption of normality.
The t-test, F-test and Z-test are parametric tests: they assume normally distributed data and test hypotheses about means or variances.
