Trophozoite of Entamoeba histolytica multiplies by

Options

A. Encystment
B. Sporulation
C. Binary fission
D. Multiple fission.

Answer

To determine how the trophozoite of Entamoeba histolytica multiplies, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Organism**: Understand that Entamoeba histolytica is a type of amoebic protozoa that is known to cause intestinal infections in humans.

2. **Understand the Trophozoite Stage**: The trophozoite is the active, feeding stage of the organism. It is important to note that this stage is responsible for growth and multiplication.

3. **Review Multiplication Methods**: The possible methods of multiplication mentioned are:
- Encystment
- Sporulation
- Binary fission
- Multiple fission

4. **Determine the Correct Method**: Research and confirm that the trophozoite of Entamoeba histolytica primarily multiplies by **binary fission**. This is a simple form of asexual reproduction where the organism divides into two identical cells.

5. **Understand the Result of Multiplication**: After binary fission, the trophozoite can produce numerous cysts. These cysts are important for the transmission of the infection as they can survive outside the host in contaminated food or water.

6. **Conclude the Answer**: Therefore, the correct answer to the question is that the trophozoite of Entamoeba histolytica multiplies by **binary fission**.

### Final Answer:
The trophozoite of Entamoeba histolytica multiplies by **binary fission**.
