The prefix that typically indicates a negative connotation is "un-." This prefix is commonly used to denote the opposite or negation of the root word it is attached to. For instance, words like "unhappy," "unfair," and "unknown" all convey a negative or opposite meaning to their respective base words—"happy," "fair," and "known."

The other prefixes listed do not primarily convey a negative meaning. "Pro-" often implies support or favor, as seen in "proactive" or "promote," whereas "trans-" signifies movement or change, such as in "transport" or "transform." On the other hand, "inter-" refers to being between or among, as in "interact" or "international." Therefore, "un-" stands out as the correct choice when identifying a prefix that indicates a negative connotation.
