The correct answer is that urinals should not exceed 120% of the number of water closets. This guideline is established to ensure that plumbing systems are designed with efficiency and functionality in mind. It maintains a balance in the distribution of plumbing fixtures, ensuring that there are enough water closets to accommodate the demands of users while also providing urinals as an additional option.

Having urinals at levels higher than 120% of water closets could lead to underutilization of the more substantial fixture (the water closet) while relying excessively on urinals. This can result in uneven wear on the plumbing infrastructure and increased maintenance issues over time. Additionally, it can affect user convenience and accessibility, particularly in facilities that require compliance with plumbing codes and regulations.

Overall, adhering to this standard aids in effective plumbing system management, operational efficiency, and user satisfaction.
