(C) The whip-like structure at one end
In Leishmania, binary fission occurs in a definite orientation in relation to the whip-like structure (flagellum) present at one end of the cell.
The passage clearly states that Leishmania has "a whip-like structure at one end of the cell" and that "binary fission occurs in a definite orientation in relation to these structures." This contrasts with Amoeba, where splitting can occur in any plane. The examiner expects you to recall this specific detail linking the flagellum to oriented fission.
