Answer :
A standard drink is C) one 1.5-ounce shot of 80 proof liquor.
The concept of a "standard drink" helps to measure and understand alcohol consumption in different types of alcoholic beverages. One standard drink contains about 0.6 ounces (14 grams) of pure alcohol. According to this definition, the following quantities constitute a standard drink:
- 12 fluid ounces of beer with about 5% alcohol content.
- 5 fluid ounces of wine with about 12% alcohol content.
- 1.5 ounces of 80-proof distilled spirits or liquor (40% alcohol content), such as gin, rum, vodka, or whiskey.
Given these definitions, option (c) one 1.5-ounce shot of 80 proof liquor is a standard drink. Options (a) and (b) do not match the definitions for a standard drink as they exceed the standard drink sizes for wine and beer, respectively.
