2 DEC SS Q.39
- Option : A
- Explanation : A valid argument is a deductive argument
that succeeds in providing decisive logical
support.
An argument is VALID in case of the following hypothetical or conditional property:
If all the premises are true, then the conclusion cannot be false; it must be true OR It is impossible for all the premises to be true but the conclusion false.
This suggests that a valid argument cannot have all true premises and a false conclusion. So, if a valid argument does have a false conclusion, it cannot have all true premises. Thus, at least one premise must be false.
