Nonparametric tests are used when the data is not normally distributed or when there is not enough data to assume a normal distribution. Nominal data can be analyzed using nonparametric tests such as chi-square test. Nonparametric tests do not require any assumptions about the underlying distribution of the population, so they are a good choice when the data is not normally distributed. Therefore, choice A is the best option.
