Signet ring stage of Plasmodium represents

Options

A. Beginning of schizogony in liver cells
B. End of schizogony in RBC
C. Beginning of schizogony in RBC
D. Beginning of sporogony in humans

Explanation

**Step-by-Step Solution:**

1. **Understanding Plasmodium and Malaria**: Plasmodium is a genus of parasitic protozoa that causes malaria in humans. It is transmitted through the bite of infected female Anopheles mosquitoes.

2. **Identifying the Signet Ring Stage**: The signet ring stage of Plasmodium refers to a specific developmental stage of the parasite when it is inside red blood cells (RBCs). At this stage, the parasite takes on a characteristic appearance resembling a signet ring, with the nucleus pushed to one side.

3. **Significance of the Signet Ring Stage**: This stage represents the beginning of a process known as schizogony, which is a form of asexual reproduction in the parasite. During schizogony, the parasite undergoes multiple nuclear divisions followed by cytoplasmic division, leading to the formation of new merozoites (the daughter cells).

4. **Location of Schizogony**: The signet ring stage indicates that the schizogony is occurring within the red blood cells. This is crucial because it is during this stage that the parasite multiplies and prepares to invade more RBCs.

5. **Conclusion**: Therefore, the signet ring stage of Plasmodium represents the beginning of schizogony in red blood cells.

**Final Answer**: The signet ring stage of Plasmodium represents the beginning of schizogony in red blood cells.
