Which abnormality is depicted in the image below?

A. Scoliosis is characterized by an abnormal lateral curvature of the spine. This can result in an uneven shoulder height and an asymmetrical rib cage when viewed from the front or back. The spine may curve to the side, creating a noticeable "S" or "C" shape. B. Lordosis, also known as hyperlordosis, is an excessive inward curvature of the lower back (lumbar spine). This condition makes the buttocks appear more prominent and the abdomen to protrude. The pelvis tilts forward, creating a pronounced curve in the lower back. C. Pigeon chest, or pectus carinatum, is a condition where the chest protrudes outward, giving it a "pigeon-like" appearance. The sternum sticks out, creating a noticeable bulge in the center of the chest. D. Kyphosis is characterized by an excessive outward curvature of the upper spine (thoracic spine), resulting in a hunchbacked or rounded appearance of the upper back. The back may appear rounded or hunched when viewed from the side.
