Lateral stability resists rotation about which axis?

Explanation:
Lateral stability is about keeping the airplane level in roll, so it resists rotation about the nose-to-tail axis, the longitudinal axis. Roll is the motion around that axis, and lateral stability works to restore wings level after a disturbance such as a gust or a banked turn. The other axes correspond to different motions: rotation about the wingtip-to-wingtip axis is pitch (lateral axis), and rotation about the vertical axis is yaw (vertical axis). So lateral stability specifically counteracts roll about the longitudinal axis.
