Options

A. forest stage
B. scrub stage
C. reed - swamp stage
D. marsh - meadow stage

Answer

To solve the question regarding the stage that comes immediately after the submerged free-floating plant stage in hydrarch succession, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Hydrarch Succession**: Hydrarch succession refers to the ecological process of succession that occurs in aquatic environments, leading to the formation of a mature ecosystem.

2. **Identify the Stages of Hydrarch Succession**: The stages of hydrarch succession typically include:
- Phytoplankton stage
- Submerged plant stage
- Free-floating plant stage
- Reed swamp stage
- Marsh meadow stage
- Forest stage

3. **Locate the Relevant Stages**: The question specifically asks for the stage that comes immediately after the submerged free-floating plant stage. Based on the stages identified:
- After the submerged plant stage, the next stage is the **free-floating plant stage**.
- Following the free-floating plant stage, the next stage is the **reed swamp stage**.

4. **Conclusion**: Therefore, the stage that comes immediately after the submerged free-floating plant stage is the **reed swamp stage**.

### Final Answer:
The stage which comes immediately after the submerged free-floating plant stage in hydrarch succession is the **reed swamp stage**.
