B. reptiles and birds
C. chimpanzee and apes
D. chordates and non-chordates

Explanation

To solve the question about Archaeopteryx being a connecting link, we can follow these steps:

### Step 1: Understand the Concept of Connecting Links
A connecting link refers to an organism that exhibits characteristics of two different groups, suggesting an evolutionary relationship between them.

### Step 2: Identify the Characteristics of Archaeopteryx
Archaeopteryx is known for having features of both birds and reptiles. It possesses wings and feathers similar to birds, but it also has teeth and a long bony tail, which are characteristics of reptiles.

### Step 3: Analyze the Options Provided
1. **Reptiles and Mammals**: This option does not fit as Archaeopteryx does not share significant traits with mammals.
2. **Reptiles and Birds**: This option is plausible since Archaeopteryx shows features of both groups.
3. **Chimpanzee and Apes**: This option is unrelated to Archaeopteryx as it does not connect to these primates.
4. **Chordates and Non-Chordates**: This option is too broad and does not specifically relate to Archaeopteryx.

### Step 4: Conclude the Correct Answer
Based on the characteristics and the analysis of the options, Archaeopteryx is indeed a connecting link between reptiles and birds, indicating that birds evolved from reptilian ancestors.

### Final Answer
The correct option is **Option 2: Reptiles and Birds**.
