Correct Answer » A
Explanation

A. i.e. The articular processes are interlocked
The thoracic vertebrae have facet joints with vertical and closely fitting articular processes, which interlock tightly.
– This arrangement provides structural stability that resists dislocation under normal physiological forces.
– Interlocking of articular processes restricts movements such as rotation and translation, preventing vertebral displacement.
