Options

A. Lobe fish
B. Dodo bird
C. Sea weed
D. Chimpanzee

Explanation

**Step-by-Step Solution:**

1. **Understand the Concept of Link Species:**
- Link species are organisms that exhibit characteristics of two different groups, serving as a bridge in the evolutionary lineage. They help illustrate the transition from one group to another.

2. **Identify the Definition:**
- The definition of link species is crucial. They are often referred to as "connecting links" because they possess traits from both ancestral and descendant groups.

3. **Examine the Options Provided:**
- Look at the options given in the question. In this case, the first option is "lobe-finned fish."

4. **Analyze the Characteristics of Lobe-Finned Fish:**
- Lobe-finned fish, such as *Coelacanths* and *Lungfish*, possess features that are characteristic of both fish and amphibians. They have fleshy, lobed fins that are structurally similar to limbs, indicating a possible evolutionary link to land-dwelling vertebrates.

5. **Determine the Correct Answer:**
- Based on the analysis, lobe-finned fish are indeed considered a link species as they connect the aquatic world of fish with the terrestrial world of amphibians. Therefore, the correct answer is the first option: lobe-finned fish.

6. **Conclude the Answer:**
- The example of a link species from the options provided is lobe-finned fish, which serves as a connecting link between fish and amphibians.

**Final Answer:**
- The correct answer is lobe-finned fish.
