1. A
   Testes \( \rightarrow \) Vasa efferentia \( \rightarrow \) Bidder's canal \( \rightarrow \) Urinogenital duct \( \rightarrow \) Cloaca.
2. B
   Testes \( \rightarrow \) Urinogenital duct \( \rightarrow \) Vasa efferentia \( \rightarrow \) Bidder's canal \( \rightarrow \) Cloaca.
3. C
   Testes \( \rightarrow \) Bidder's canal \( \rightarrow \) Vasa efferentia \( \rightarrow \) Urinary bladder \( \rightarrow \) Cloaca.
4. D
