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

  1. 750 mm

  2. 850 mm

  3. 950 mm

  4. 1050 mm

The correct answer is: 850 mm

The correct answer is B 850 mm. The minimum height required for a handrail on a stairway in a residential building is determined by building codes and regulations, and in many cases, it is 850 mm. Options A (750 mm), C (950 mm), and D (1050 mm) are not correct as they do not meet the minimum height requirement for a handrail on a stairway. Option A is too low, while options C and D are too high. It is important to follow building codes and regulations for the safety of residents.
