Select the correct statement.

Options

A. Tendril of a pea plant and phylloclade of Opuntia are homologous.
B. Tendril of a pea plant and phylloclade of Opuntia are analogous.
C. Wings of birds and limbs of lizards are analogous.
D. Wings of birds and wings of bat are homologous.

Explanation

To solve the question of selecting the correct statement regarding homologous organs, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- Define homologous organs: These are organs that have the same origin but may perform different functions.
- Define analogous organs: These are organs that perform similar functions but have different origins.

2. **Analyze the First Statement**:
- The first statement claims that the tendril of the pea plant and the phylloclade of the Opuntia are homologous.
- Identify the nature of both structures:
- The tendril of the pea plant is a modified shoot that helps the plant climb.
- The phylloclade of Opuntia is also a modified shoot, but it primarily functions in photosynthesis.

3. **Compare the Functions and Origins**:
- Both the tendril and phylloclade are modified shoots, indicating they share a common origin.
- They perform different functions: climbing (tendril) vs. photosynthesis (phylloclade).

4. **Conclusion**:
- Since both structures are derived from the same type of organ (shoots) and perform different functions, they are indeed homologous.
- Therefore, the first statement is correct.

5. **Identify Incorrect Options**:
- The question implies there are other statements to consider, but since we have established the first statement is correct, the remaining options must be incorrect.

### Final Answer:
The correct statement is: "The tendril of the pea plant and the phylloclade of the Opuntia are both homologous."
