C is correct. Nominal data are categorical values that are not amenable to being organized in a logical order.

A is incorrect because ordinal data are categorical data that can be logically ordered or ranked.

B is incorrect because discrete data are numerical values that result from a counting process; thus, they can be ordered in various ways, such as from highest to lowest value.

名义数据是分类值，不适合按逻辑顺序组织。

A 不正确，因为序数数据是可以按逻辑排序或排名的分类数据。

B 不正确，因为离散数据是计数过程产生的数值； 因此，它们可以以各种方式排序，例如从最高值到最低值。
