Select and explain.

Answer: B: Remnant of mesonephric duct 
Explanation: Ganer's duct cyst arises from incomplete regression of the vaginal poion of the Wolffian (mesonephric) ducts. Ganer's ducts are determined by the presence of persistent remnants of mesonephric ducts. Since the mesonephric ducts have secretory propeies, cysts can develop. Usually, cysts located along the anterior-lateral vaginal wall, matching the Wolffian duct path, are <=2 cm in size and asymptomatic.
