### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the term that refers to the axis of the inflorescence.

2. **Evaluating the Options**:
- **Option 1: Penduncle**: This is defined as the main axis of an inflorescence, which bears the flowers or fruits. Therefore, this option is likely correct.
- **Option 2: Thalamus**: This is the thickened part of the stem from which the flower organs grow in angiosperms. It does not refer to the axis of the inflorescence, making this option incorrect.
- **Option 3: Petiole**: This is the stalk that joins the leaf base to the leaf blade. It is not related to inflorescence, so this option is also incorrect.
- **Option 4: Pedicel**: This refers to the stem that attaches a single flower to the inflorescence. While it is part of the flower structure, it does not represent the axis of the inflorescence itself, making this option incorrect.

3. **Conclusion**: After evaluating all the options, the correct answer is **Penduncle**, as it is the term that specifically refers to the axis of the inflorescence.

### Final Answer:
