In Entamoeba histolytica, the presence of chromatid bodies is characteristic of

Options

A. precystic stage
B. mature quadrinucleate stage
C. trophozoite stages
D. mature binucleate stage .

Explanation

To solve the question regarding the presence of chromatid bodies in Entamoeba histolytica, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Organism**: Recognize that Entamoeba histolytica is a protozoan parasite that can exist in different forms during its life cycle, including trophozoites and cysts.

2. **Identify the Stages**: The life cycle of Entamoeba histolytica includes several stages:
- Trophozoite stage
- Pre-cystic stage
- Mature cyst stage (which can include quadrenucleate and binucleate forms)

3. **Define Chromatid Bodies**: Chromatid bodies are structures found within the cell that are associated with the genetic material. In the context of Entamoeba histolytica, these bodies are present in certain stages of its life cycle.

4. **Locate the Presence of Chromatid Bodies**: According to the information provided, chromatid bodies are specifically associated with the pre-cystic stage of Entamoeba histolytica. They are cigar-shaped bodies made up of crystalline ribosomes.

5. **Eliminate Incorrect Options**:
- The mature quadrenucleate stage and mature binucleate stage do not have chromatid bodies as they are more developed forms.
- The trophozoite stage is also not characterized by the presence of chromatid bodies.

6. **Conclude the Correct Answer**: Based on the information, the presence of chromatid bodies is characteristic of the pre-cystic stage of Entamoeba histolytica.

### Final Answer:
The presence of chromatid bodies in Entamoeba histolytica is characteristic of the **pre-cystic stage**.
