The requirement for the egress width of a stairway in an office building is based on safety regulations that ensure a sufficient escape route during emergencies. The code typically specifies that the minimum width must allow for the safe and efficient movement of occupants.

The correct choice, which indicates a requirement of 0.2 inches per occupant, aligns with standards for egress design as it effectively accommodates the number of occupants likely to use the stairway at any given time. This figure is derived from building codes that aim to prevent bottlenecks and allow for a smooth and quick exit during emergency situations.

While the other options suggest different increments for width, they do not meet the established standards that have been determined to ensure adequate safety levels for occupants in buildings.
