The required dimensions of the turnabout space along corridors for persons with disabilities (PWD) use are established to ensure that individuals who may rely on mobility devices, such as wheelchairs, have enough room to maneuver and turn around safely. The correct dimensions of 1.5 m x 1.5 m provide a sufficient area for a typical wheelchair to navigate, allowing for a smooth and safe turning motion without risk of collision or difficulty in movement. This size ensures compliance with accessibility standards, which aim to create inclusive environments for all users.

The other options do not meet the necessary specifications for safe and effective maneuverability in a corridor. For instance, dimensions smaller than what is specified may restrict movement and cause accessibility concerns, potentially leading to safety issues for users trying to navigate tight spaces.
