Which of the following provides an example of a fallacy of inconsistency?

A fallacy of inconsistency occurs when an argument contradicts itself or makes claims that cannot logically coexist. The statement, "There are exceptions to all general statements," illustrates this concept because it asserts a general rule—that all general statements have exceptions—while inherently contradicting itself. If all general statements have exceptions, then the general statement itself that "there are exceptions to all general statements" cannot be an absolute truth without exceptions, thus creating an inconsistency.

The other options do not exemplify inconsistency in the same way. The plea for help because of parental disappointment focuses on an emotional appeal rather than presenting contradictory claims. The assertion of guilt based on a lack of evidence also involves logical reasoning but does not express a contradictory premise. Lastly, the question about cheating could imply a behavior that the person may or may not have stopped, but it does not present conflicting statements about itself.
