How many spinal nerves are there in the thoracic region?

Explanation:
The number of spinal nerves in the thoracic region matches the number of thoracic vertebrae, so there are twelve thoracic spinal nerves. Each nerve is named for and exits below its corresponding vertebra, giving the pairs labeled T1 through T12. That’s why the correct count is twelve. The other options would imply an off-by-one error or an extra nerve that doesn’t align with the actual vertebral count in the thoracic area.
