(Z)-2-Butene reacts with Br_(2)//H_(2)O . The resulting bromohydrin when treated with methoxide in methanol undergoes an intramolecular S_(N^2) reaction. Taking into consideration the stereochemical consequences of the reaction mechanism involved, choose the final product(s) of these transformations.
