Explanation:

This question tests knowledge of standard unit conversions within the imperial system of measurement. In the avoirdupois system, which is commonly used for everyday measurements in countries like the United States, one pound (lb) is precisely defined as being equal to 16 ounces (oz). This is a fixed conversion factor. Options B, C, and D represent incorrect conversion values for pounds to ounces. Therefore, $1 \text{ pound} = 16 \text{ ounces}$.
