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: 850 mm

The minimum height required for a handrail on a ramp in a residential building is 850 mm. This is determined by building codes and regulations to ensure the safety of individuals using the ramp. Option A (750 mm) is too low and may not provide enough support for someone walking up or down the ramp. Option C (950 mm) and D (1050 mm) are too high and may be difficult for some individuals, such as children or individuals with disabilities, to reach. Therefore, option B is the most appropriate height for a handrail on a ramp in a residential building.
