Option 1 states that both the assertion (A) and the reason (R) are individually true, and that R is the correct explanation of A.

To evaluate this option, we need to first examine the assertion, which states that little rotation and bending of the vertebral column is possible. This assertion is generally true. While some degree of rotation and bending can occur in the vertebral column, it is relatively limited due to the structure and arrangement of the vertebrae.

Moving on to the reason provided, it states that this limited rotation and bending is due to the presence of fibrous joints between the vertebrae. This reason is incorrect. The limited movement of the vertebral column is primarily due to the interlocking nature of the vertebrae themselves, rather than the presence of fibrous joints. The interlocking structure between vertebrae helps provide stability and support to the spine, but it restricts excessive movement.

Therefore, since the reason provided in option 1 is incorrect, this option is not the correct explanation for the assertion.

Option 2 states that both the assertion and the reason are individually true, but the reason is not the correct explanation for the assertion. This option is correct, as explained above.

Option 3 states that the assertion is
