1 pound = _____ ounces

16

The correct answer is option 1. 16.

In the imperial system of measurement, 1 pound (lb) is equivalent to 16 ounces (oz). This means that if you have 1 pound of a substance, it would weigh the same as 16 ounces of that substance. This relationship is commonly used in everyday situations where weight is measured in the imperial system, such as when purchasing groceries or weighing ingredients for cooking.
