Nonparametric tests do not require assumptions about the distribution of populations being compared, so option C (the requirement of normally distributed populations) will never be a required condition of a nonparametric test. Options A and B are possible, as nonparametric tests can be used with both ordinal and interval data. Option D may or may not be a required condition, depending on the specific nonparametric test being used.
