Answer 1

The correct option is B 5 vertebrae

The sacrum is a part of the vertebral column. It is formed by the fusion of 5 bones. It is a large, triangular bone at the base of the spine. The main function of the sacrum is to connect the spine to the hip bones (iliac). The sacrum is a very strong bone that supports the weight of the upper body as it is spread across the pelvis and into the legs. Thus, the correct answer is option A.
