A logical fallacy is

1. A flagrant lie

2. An overestimation of a statement

3. An argument that lacks credibility

4. A false assumption in an argument

The correct answer is: A false assumption in an argument

A logical fallacy is a flaw in reasoning that makes an argument invalid or unsound. It occurs when the premises do not provide enough evidence to support the conclusion, which can lead to false conclusions. Choices A, B, and C are incorrect because they do not fully capture the definition of a logical fallacy. A flagrant lie may be used as evidence in an argument, but it is not the flaw in reasoning itself. An overestimation of a statement may result in an unsound argument, but it is not necessarily a logical fallacy. An argument lacking credibility can contain valid reasoning, but the overall argument may be flawed due to other factors. Therefore, these options do not accurately define a logical fallacy.
