The correct answer is D
A-alpha fibers - the largest myelinated fibers, range in diameter from 7-16 microns,conduction velocity from 70-120m/s, encoded for the transmission of muscle spindle and tendon organ afferents
A-beta fibers - responsible for sensibility of touch, diameter from 6-8 microns, conduction velocity 30-70 m/s.
A-delta fibers - transmit stimuli encoded for temperature and fast or first pain, smallest myelinated, diameter 2.5-4 microns, conduction velocity 12-30 m/s
Unmyelinated C fibers - transmit stimuli encoded for slow or second pain, temperature, efferent sympathetic fibers, conduction velocity 0.5-2 m/s.
