A single story

This option incorrectly states the square footage of the occupancy. The number of risers required is based on the total area, and if it is inaccurately reported, it will lead to an incorrect assessment of the required fire safety measures.

This choice suggests that only one riser is needed, which is typically insufficient for a building of this size. The actual requirement may vary based on the specific area and local building codes, indicating that more than one riser is likely necessary for adequate protection.

While two risers might seem reasonable, it may not meet the total square footage requirements for fire safety. The actual number of risers needed depends on precise calculations based on the building's specifications, which may indicate a higher number is necessary.

This option overestimates the number of risers required for a single story ordinary hazard occupancy without specific justification. Unless detailed calculations support the need for four risers, this choice does not align with common building safety standards.

Similar to the previous choice, proposing six risers is likely excessive for a single story building, depending on its actual size. Such a high number suggests a misunderstanding of the riser requirements based on the area and occupancy classification.
