Explanation

To determine the correct sequence of succession in a pond, we need to understand the stages of ecological succession that occur in a newly formed water body, known as hydroseres. Here is a step-by-step breakdown of the process:

### Step 1: Identify Initial Stages
In a newly formed pond, the first organisms to appear are plankton. Specifically, phytoplankton (algae) are the first to colonize the water body, followed by zooplankton.

**Hint:** Remember that plankton are the pioneers in aquatic ecosystems.

### Step 2: Submerged Plants
After plankton, rooted and submerged plants, known as hydrophytes, start to grow. These plants anchor themselves to the bottom of the pond and are essential for stabilizing the ecosystem.

**Hint:** Think of submerged plants as the foundation of the aquatic ecosystem.

### Step 3: Floating Plants
Once submerged plants are established, floating plants begin to appear. These plants float on the surface of the water and are important for providing shade and habitat for aquatic life.

**Hint:** Floating plants are crucial for surface coverage in the pond.

### Step 4: Reed Swamp Stage
Following the establishment of floating plants, the reed swamp stage occurs. This stage is characterized by the growth of tall, marshy plants that thrive in wet conditions.

**Hint:** Reed swamps indicate a transition to more complex plant communities.

### Step 5: Sedges
After the reed swamp stage, sedges (a type of grass-like plant) become prominent. This stage signifies further development of the ecosystem, leading towards a more mature state.

**Hint:** Sedges are often found in wetland areas and indicate a stable ecosystem.

### Step 6: Climax Community
Eventually, as the ecosystem matures, it may lead to a scrub stage or climax community, where woody plants and trees may start to appear, completing the succession process.

**Hint:** The climax community represents the final stage of ecological succession.

### Conclusion
Based on the above steps, the correct sequence of succession in a pond is:
1) Submerged plants → 2) Floating plants → 3) Reed swamp stage → 4) Sedges.

Thus, the correct answer to the question is **Option 1**.
