When stacking loose brick above a height of 4 feet, it is essential to arrange them in a manner that promotes stability and safety. Tapering back the stack by 2 inches for every foot of height is a method that helps prevent the bricks from toppling over due to their weight and the risk of external forces such as wind or movement around the stack.

This tapering technique creates a wider base, ensuring a lower center of gravity, which is crucial for maintaining balance. The gradual reduction in the stack's width as the height increases safeguards against potential collapses that could lead to injuries or property damage. Thus, adhering to this guideline not only complies with safety regulations but also enhances the overall safety of the construction site.

The other methods, while potentially beneficial in specific contexts, do not address the inherent risks associated with stacking materials at height as effectively as the tapering technique does. Therefore, the correct choice emphasizes the importance of safe stacking practices to mitigate hazards.
