Answer: 3. Testes \(\rightarrow\) Vasa efferentia \(\rightarrow\) Kidney \(\rightarrow\) Bidder's canal \(\rightarrow\) Urinogenital duct \(\rightarrow\) Cloaca

In a male frog, sperms travel: testes \(\rightarrow\) vasa efferentia \(\rightarrow\) kidney (through Bidder's canal) \(\rightarrow\) urinogenital duct \(\rightarrow\) cloaca.

Option 3 matches this order. Option 1 adds a seminal vesicle, option 2 uses a ureter, and option 4 reverses the order of structures.
