The correct answer is based on established engineering principles that quantify the lateral load induced on a structure that is not vertical. When a building is out of plumb, it creates an imbalance affecting its stability and introduces lateral forces that need to be accounted for in structural assessments.

According to general rules, the lateral load is calculated as 1% of the building's weight for every 1% that the building is out of plumb. This means that if a building is leaning or tilted, there is a specific amount of lateral force acting on it proportional to how much it is out of vertical alignment.

For example, if a building weighs 100,000 pounds and is 2% out of plumb, the lateral load would be 2,000 pounds (1% of the building's weight for each percent of tilt). This calculation assists engineers and rescuers in understanding the potential risk and necessary precautions for managing the structure, especially during rescue operations following a structural failure or collapse.

The other choices do not align with the standard calculation for lateral loads in relation to the degree of being out of plumb, which can lead to unsafe assessments of the building's stability.
