Which Statement Represents the Correct Order of the Reflex Arc

Which statement represents the correct order of the reflex arc for micturition?

A) The reflex arc begins with stretch receptors sending signals to the sacral region of the spinal cord - stretch receptors receive signals in the urinary bladder's walls - the detrusor muscle contracts the internal urethral sphincter relaxes - parasympathetic neurons go from the spinal cord to the detrusor muscle - urine is passed.
