36. Cutting a lumbar spinal nerve, distal to the white and grey rami would alter A) sensory input. B) somatic motor output c) D) and E) A, B, and C sympathetic motor output A C

Solution

option D is the right answer

The grey and white ramus are responsible for the sympathetic motor output as well as they are also responsible for the sensory input from the organs as they have general visceral efferent fibres whose primary cell body resides in dorssal root ganglion

The grey ramus also contains the postganglionic nerve fibre of the sympathetic nervous system

So option D is the right answer
