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.
