Perhaps you recall from your introductory texts that for spinal segments, this typically means full extension. That's when the joint surfaces, surprisingly, are most congruent, and the surrounding ligaments are, gasp, under maximum tension. Option (C), with its fanciful description of a compound movement, clearly fails to represent the thoracic spine's most stable physical state. It's almost as if some basic principles apply.
2. A Modest Triumph: This question, rated as medium difficulty, simply aims to separate those who bother to distinguish between "resting position," "closed-packed position," and "capsular pattern." These aren't exactly obscure, esoteric concepts. The added "complexity" of thoracic ribs seems to be a stumbling block for many, but you, apparently, navigated it.
