Solution

The correct option is B Lumbar vertebrae
The vertebral column consists of 26 bones known as vertebrae. They are divided into cervical (7), thoracic (12), lumbar (5) sacral (5) and coccygeal (4) vertebrae.
Cervical vertebrae are present in the neck.
Thoracic vertebrae are present at the chest level. They join with the ribs.
Lumbar vertebrae are present in the lower back. They are the largest and the strongest of all the vertebrae as they have to bear the weight of the whole body when the body is in standing position.
The sacral vertebrae has 5 fused bones.
The coccygeal vertebrae has 4 fused bones.
