It is impossible for a valid argument to have A. true premises and a false conclusion. B. true premises and a true conclusion. C. false premises and a false conclusion. D. none of the above

A). True premises and a false conclusion.

Explanation:

As per the question, it is impossible for a valid argument to have 'true premises and false conclusion' because such an argument would be considered 'invalid'. Such a combination makes the argument invalid due to the failure of logic as the premises in an argument primarily functions to support an argument and its conclusion and thus, true premises cannot support a false conclusion. However, the vice versa(false premises and true conclusion) could be possible as premises may or may not justify the truth of the conclusion but if the premises are true, it becomes impossible for the conclusion to be false logically. Therefore, option A is the correct answer.
