The key idea is how collagen from bones creates body in stock. When bones (often with connective tissue) are simmered for a long time, the collagen dissolves and turns into gelatin, giving stock a rich, set-with-cool temperature texture. That gelatinization is the defining difference from broth, which is typically made from meat and vegetables and is valued for a lighter, more straightforward liquid rather than a gel-like body. So the statement that stock extracts collagen from bones to form gelatin correctly describes what gives stock its characteristic texture and distinguishes it from broth. The other statements either misstate the source (broth from bones) or the result (stock and broth being the same, or stock being inherently lighter in flavor), so they don’t capture this essential distinction.
