The LOD of a push is P-A, I-S, and L-R. Which listing does this represent?

Explanation:
Think of the line of drive as describing three directional components of a push: posterior to anterior, inferior to superior, and left to right. In the listing system, you start with the side (Left) and then encode those three directions as Posterior–Inferior–External (the “External” part indicating the lateral/external orientation). The combination Left Posterior-Inferior-External matches the described push: P-A means pushing from back toward the front, I-S means pushing upward, and left-to-right means a lateral move to the outside. So the correct listing is Left Posterior-Inferior-External. The other options miss one or more components of the three-direction description, or don’t capture all aspects of the push.
