Which of the following outlines the required minimum clear height for wheelchair accessibility under tables?

The requirement for wheelchair accessibility under tables is based on ensuring that individuals using wheelchairs can comfortably fit underneath with adequate space for movement. The standard minimum clear height established for this purpose is 740 mm. This height allows for sufficient room for various wheelchair designs, accommodating both the height of the wheelchair and the needs of the user for accessing the table easily.

This standard aligns with accessibility guidelines, which aim to promote inclusivity in public and private spaces by ensuring that tables and similar fixtures can be used by people with disabilities. The other heights listed do not meet this accessibility requirement, which is why they do not qualify as the minimum clear height necessary for tables to ensure they are accessible to all users.
