What is the minimum height required for a guardrail on a balcony in a residential building?

  1. 900 mm

  2. 1000 mm

  3. 1100 mm

  4. 1200 mm

The correct answer is: 1100 mm

The minimum height required for a guardrail on a balcony in a residential building needs to be 1100 mm. This is because according to building codes and regulations, a balcony guardrail must be at least 42 inches high for safety reasons. The other options are incorrect because they do not meet the minimum height requirement, making them potential safety hazards for residents. The option A, at 900 mm (35 inches), is too short and can be easily climbed over. The options B and D, at 1000 mm and 1200 mm respectively, are also below the required height and may not provide adequate protection. Therefore, the correct answer is C, 1100 mm.
