Homologous organs have :

Options

A. Similar origin and dissimilar functions,
B. Dissimilar origin and structure
C. Dissimilar origin and function
D. Dissimilar origin and similar functions

Answer

### Step-by-Step Text Solution:

1. **Understanding Homologous Organs**:
- Homologous organs are defined as organs that have a similar origin but may serve different functions in different species.

2. **Analyzing the Options**:
- The options provided are:
- A) Similar origin and dissimilar functions
- B) Dissimilar origin and structure
- C) Dissimilar origin and function
- D) Dissimilar origin and similar function

3. **Identifying the Correct Characteristics**:
- For homologous organs, we need to establish that they share a common origin (similar origin) and that their functions are different (dissimilar functions).

4. **Evaluating Each Option**:
- **Option A**: Similar origin and dissimilar functions - This aligns with the definition of homologous organs.
- **Option B**: Dissimilar origin and structure - This does not apply to homologous organs.
- **Option C**: Dissimilar origin and function - This also does not apply to homologous organs.
- **Option D**: Dissimilar origin and similar function - This describes analogous organs, not homologous.

5. **Conclusion**:
- The correct answer is **Option A: Similar origin and dissimilar functions**.
