Options

A. Taenia
B. Plasmodium
C. Leishmania
D. Wuchereria

Answer

To solve the question about the formation of the Cysticercus larva, we will analyze the options provided and identify the correct one step by step.

### Step 1: Understand the term "Cysticercus larva"
Cysticercus larva is a specific larval stage of certain parasitic flatworms. It is important to know which organism produces this larval form.

### Step 2: Analyze the options
1. **Tenia (Taenia solium)**: This is a genus of tapeworms, and the larval form is known as Cysticercus. This option seems promising.
2. **Plasmodium**: This is a genus of parasites that cause malaria. It does not produce Cysticercus larva.
3. **Leishmania**: This genus causes leishmaniasis and does not produce Cysticercus larva.
4. **Wuchereria**: This genus is responsible for lymphatic filariasis and does not produce Cysticercus larva.

### Step 3: Identify the correct answer
Based on the analysis, the only organism that produces Cysticercus larva is **Tenia (specifically Taenia solium)**. Therefore, the correct answer is the first option.

### Final Answer
Cysticercus larva is formed in the history of **Tenia (Taenia solium)**.
