The ureter is identified at operation by:: (A) Rich arterial plexus, (B) Peristaltic movement, (C) Relation to lumber plexus, (D) Accompanied by renal vein
Answer is B. At operation, the ureter is recognized by:

Its pale glistening appearance
By a fine longitudinal plexus of vessels on its surface
More particularly by its peristaltic movement
By palpation between finger and thumb as a firm cord which, when escapes, gives a characteristic 'snap'.

The absence of pulsation does not serve to identify a structure as ureter because veins and obliterated umbilical artery are also non-pulsatile.
