A. Consumers and firms use all available information as they act to achieve their goals

Explanation:

Information is a value, maybe the most important. It´s also scarce and expensive: business pay fortunes to smart men.

And the most worthy information is the one that allows a person to predict the futuro. For instance, who knows what will be the price of oil in one year.
