What does it mean to be paraplegic?

Being paraplegic specifically refers to a condition where an individual experiences paralysis affecting both legs and the lower part of the torso. This paralysis typically results from injury or damage to the spinal cord, especially in the thoracic or lumbar regions, which inhibits the brain's ability to send signals to the lower body. As a result, individuals may lose motor control and sensation in their legs, necessitating the use of wheelchairs or other assistive devices for mobility.

In this context, the other options do not accurately describe the condition of paraplegia. Being paralyzed from the neck down relates to quadriplegia, which affects all four limbs and is a more severe form of paralysis. Experiencing partial loss of movement in the arms also does not align with the definition of paraplegia, as it pertains to upper limb movement rather than paralysis of the lower body. Lastly, having full mobility but with severe pain would not relate to paralysis at all, as it implies the ability to move normally despite discomfort. Therefore, option B clearly defines the condition of paraplegia, focusing on the paralysis specifically affecting the legs and lower torso.
