The classification of "non-" as a negative word stems from its function in language. This prefix is used to indicate the absence or negation of the word to which it is affixed. For instance, in words like "nonexistent" or "noncompliant," the prefix "non-" conveys a sense of negation, meaning that something does not exist or does not comply with certain standards.

In contrast, the other options do not serve the same negative function. Words like "always" and "most" imply frequency or prevalence, while "positive" denotes an affirmative or constructive quality. Therefore, "non-" stands out as the only option that inherently alters the meaning of the root word to reflect a negative condition or absence.
