​Which of the following is incorrect?​

Correct option is D

Falsity is an attribute of an argument→ Incorrect

Falsity applies to propositions(e.g., a false statement), not to arguments as a whole. Arguments are judged asvalid/invalidorsound/unsound, not "true/false."

Information booster: 

1. Truth and falsity are semantic properties that apply to individual propositions or statements.

2. An argument is a set of propositions, where some serve as premises and one as the conclusion.

3. Validity of an argument refers to the formal logical connection between premises and conclusion, not their actual truth.

4. An argument can be valid but have false premises, making its conclusion false.

5. Invalidity means the argument’s logical structure does not guarantee the conclusion’s truth.

6. Understanding the difference between propositional attributes (truth/falsity) and argument attributes (validity/invalidity) is key in logic.
