What is the minimum clearance required for a door in a commercial building?

750 mm
800 mm
850 mm
900 mm

The correct answer is: 900 mm

A door in a commercial building should have a minimum clearance of 900 mm. This allows for wheelchair access and for people to easily pass through, while also ensuring that the door meets safety and accessibility standards. Option A (750 mm) is too narrow and would not allow for easy passage or wheelchair accessibility. Option B (800 mm) is still too narrow and does not meet safety and accessibility standards. Option C (850 mm) is also too narrow and does not meet the minimum clearance requirement for a commercial building door. Therefore, D (900 mm) is the correct answer as it allows for sufficient clearance for easy access and meets safety and accessibility standards.
