w choose
x choose
y choose
z choose

Explanation:

To solve this, we analyze the vertebral column regions:

For region \( W \):

The topmost (red) region in the diagram is the Cervical region (supports the neck, 7 vertebrae).

For region \( X \):

The blue, middle-upper region is the Thoracic region (attaches to ribs, 12 vertebrae).

For region \( Y \):

The yellow, middle-lower region is the Lumbar region (supports the lower back, 5 vertebrae).

For region \( Z \):

The bottom (green) region is the Sacral/Coccygeal (Sacrum + Coccyx; Sacrum is fused, Coccyx is the tailbone).

Answer:

s (matching each label):

• \( W \): Cervical
• \( X \): Thoracic
• \( Y \): Lumbar
• \( Z \): Sacral (or Sacrococcygeal)

(Note: If options include “Cervical”, “Thoracic”, “Lumbar”, “Sacral”/“Coccygeal”, select those for their respective labels.)
