What is the standard drink size of Scotch Whiskey?

Explanation:
A standard drink is defined as containing about 10 grams of pure alcohol. Scotch whisky is typically 40% alcohol by volume. To find the volume that provides 10 g of ethanol, use volume = mass / (ABV × density). With ethanol density about 0.789 g/mL, the calculation is 10 g ÷ (0.40 × 0.789 g/mL) ≈ 31.7 mL, which rounds to about 32 mL. So the standard drink size for Scotch whisky is about 32 mL. The other options are not correct because they don’t align with the 10 g ethanol standard for a single standard drink, or they represent packaging sizes rather than a standard measure of alcohol content.
