Trace the correct route followed by sperms in a male frog from their site of origin to their discharge:

1. Testes \( \rightarrow \) Vasa efferentia \( \rightarrow \) Bidder's canal \( \rightarrow \) Urinogenital duct \( \rightarrow \) Cloaca.
2. Testes \( \rightarrow \) Urinogenital duct \( \rightarrow \) Vasa efferentia \( \rightarrow \) Bidder's canal \( \rightarrow \) Cloaca.
3. Testes \( \rightarrow \) Bidder's canal \( \rightarrow \) Vasa efferentia \( \rightarrow \) Urinary bladder \( \rightarrow \) Cloaca.
4. Testes \( \rightarrow \) Mesorchium \( \rightarrow \) Urinary bladder \( \rightarrow \) Urinogenital duct \( \rightarrow \) Cloacal aperture.
