Solution
The correct option is D The spinal cord seemed damaged A spinal cord injury occurs when there is damage to the spinal cord either from trauma, loss of its normal blood supply, or compression from tumor or infection. If the injury to the spinal cord occurs lower in the back it can cause paraplegia-paralysis of both legs only.
So, the correct option is "B" (The spinal cord seemed damaged).
