What is the minimum height required for a handrail on a ramp in a residential building?

1. 750 mm

2. 850 mm

3. 950 mm

4. 1050 mm

The correct answer is: 950 mm

The minimum height required for a handrail on a ramp in a residential building is 950 mm. This height is specified by building codes and regulations to ensure the safety of individuals using the ramp. Option A (750 mm) and B (850 mm) are too low and may not provide enough support for someone using the ramp, while option D (1050 mm) is too high and may be difficult for someone to grip or use effectively. It is important for the handrail to be at the appropriate height in order for it to serve its purpose and assist individuals in safely navigating the ramp.
