Verified step by step guidance

1. Understand the concept of a 'standard drink' in the context of stress and health psychology, which is used to quantify alcohol consumption consistently across different types of alcoholic beverages.
2. Recognize that a standard drink is defined by the amount of pure alcohol it contains, rather than the volume of the beverage itself, because different drinks have varying alcohol concentrations.
3. Recall that health guidelines, such as those from the National Institute on Alcohol Abuse and Alcoholism (NIAAA), define a standard drink as containing 14 grams of pure alcohol.
4. Compare the given options (14 grams, 8 grams, 5 grams, 20 grams) to this standard definition to identify the correct amount of pure alcohol in a standard drink.
5. Conclude that the correct answer corresponds to the option that matches the established standard of 14 grams of pure alcohol per standard drink.
