1. 5

2. 10

3. 20

4. 25

The correct answer is: 20

The correct choice, indicating that the bottom of handrail surfaces shall not be obstructed for more than 20% of their length, aligns with building codes designed to ensure safety and accessibility. Handrails are critical for providing support and stability, particularly in stairways and other elevated surfaces. Having the bottom of a handrail unobstructed for at least 80% of its length allows individuals to grasp the rail securely and prevents potential accidents that could arise from obstructed or difficult-to-hold handholds. This standard takes into account the need for users to have a clear and reliable grip, especially for those who may require additional support, such as the elderly or those with disabilities. Thus, limiting obstructions to no more than 20% of the handrail length helps maintain the functionality and safety of the rail, contributing to overall compliance with accessibility standards and enhancing the safety of those using stairs and elevated platforms.
