Which best supports the claim that the argument in the last three sentences of section one is valid? a) it is possible for both its premises to be true and its conclusion to be false. b) the premise can be determined to be true and the conclusion follows that premise. c) some support for the valid conclusion must exist to demonstrate its truth. d) this argument is valid because it leads to its own conclusion.

The correct answer is option "B": The argument is valid if the premise can be determined to be true and the conclusion follows that premise.  

For a valid argument, the conclusion must logically follow from the premises. According to a deductively valid argument, if the premises about the argument are true, its conclusions must be also true; since there is no possiblity that the conclusions are false with true premises. Besides, false premises are followed by false conclusions. However, false premises can have true conclusions. But a true premise cannot have a false conclusion.
