Identify the correct type of postural disorder from the picture given below:

The correct option is Scoliosis.

Image Analysis:
By examining the provided picture, we can observe two anatomical diagrams illustrating spinal alignment:
- Left Diagram (Normal Alignment): Labeled with the text "STRAIGHT SPINE", showing a normal, healthy spine highlighted in blue that runs straight vertically down the center of the body.
- Right Diagram (Postural Disorder): Labeled with the text "SCOLIOSIS", showing a spine highlighted in reddish-orange that deviates from the central vertical line and curves sideways in an "S" or "C" shape.

Detailed Explanation:
- Scoliosis is a postural deformity characterized by an abnormal lateral (sideways) curvature of the spine. As visible in the right skeleton illustration, this curvature causes the vertebral column to bend to the side rather than maintaining a straight vertical line.
- Knock Knee (Genu valgum) is a postural deformity of the lower limbs where the knees bend inward and touch each other when standing.
- Bow Leg (Genu varum) is a condition where the knees bend outward, leaving a wide gap between the knees when standing with feet together.
- Lordosis is an increased inward curvature of the lower spine (lumbar region), creating a swayback appearance when viewed from the side.
