• A. Amoeba
• B. Paramecium
• C. Leishmania
• D. All the above

2. Binary fission occurs in unicellular organisms like Amoeba, Paramecium, and Leishmania.

Explanation of incorrect option:

Option A:

Amoeba cells split into two cells by the process of binary fission of asexual reproduction.

Option B:

Paramecium cells split into two cells by the process of binary fission of asexual reproduction.

Option C:

The whip-like structure of Leishmania is split into two cells by the process of binary fission of asexual reproduction.

Final answer: Hence the correct option is D.
