THE COMMON HEPATIC DUCT IS FORMED BY THE DUCTS OF ductus choledochus ductus hepaticus dexter ductus cysticus ductus hepaticus sinister

The correct answer is: ductus hepaticus sinister.<br /><br />The common hepatic duct is formed by the union of the ductus hepaticus sinister (left hepatic duct) and the ductus hepaticus dexter (right hepatic duct). These ducts drain bile from the liver and converge to form the common hepatic duct, which then continues as the common bile duct.
