If an argument does not commit a fallacy, it is

A.necessarily valid.
B.necessarily sound.
C.Not enough information to determine
D.Both A and B

If an argument does not commit a fallacy, it means that there are no logical errors or flaws in the reasoning of the argument. However, it does not necessarily mean that the argument is valid or sound.

To determine if an argument is valid, we need to check if the conclusion logically follows from the premises. In other words, if the premises are true, does the conclusion necessarily have to be true? If the argument is valid, it means that the conclusion cannot be false if the premises are true.

To determine if an argument is sound, we need to check if it is valid and if all its premises are true. In other words, not only does the conclusion logically follow from the premises, but the premises are also true. A sound argument is both valid and has true premises.

Therefore, the correct answer is C. Not enough information to determine. Just because an argument does not commit a fallacy does not necessarily mean that it is valid or sound. Additional information is needed to determine the validity and soundness of the argument.
