The wrongly mathced pair w.r.t. the organisms and their probable time of evolution is

Options

A. Jawless fish- around 350 mya
B. Lobefins - around 350 mya
C. Fish-like giant reptiles-around 320 mya
D. Sea weeds- around 320 mya

Answer

To determine the wrongly matched pair with respect to organisms and their probable time of evolution, we need to analyze the evolutionary timeline of various organisms. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the Evolutionary Timeline
- **2,000 million years ago**: The first cellular forms of life originated.
- **500 million years ago**: The origin of invertebrates.
- **350 million years ago**: The emergence of jawless fishes and lobe-finned fishes.
- **320 million years ago**: The appearance of certain seaweeds and aquatic plants.
- **200 million years ago**: The existence of amphibians and the fish-like reptile Ichthyosaurus.

### Step 2: Analyze Each Organism and Its Timeframe
- **Jawless fishes**: Correctly matched with 350 million years ago.
- **Lobe-finned fishes**: Correctly matched with 350 million years ago.
- **Seaweeds**: Correctly matched with 320 million years ago.
- **Ichthyosaurus (fish-like reptile)**: Incorrectly matched with 320 million years ago; it actually existed around 200 million years ago.

### Step 3: Conclusion
The wrongly matched pair is the **Ichthyosaurus**, which is incorrectly associated with 320 million years ago instead of 200 million years ago.

### Final Answer
The wrongly matched pair with respect to the organisms and their probable time of evolution is **Ichthyosaurus - 320 million years ago**.
