To determine which of the following options represents examples of stem and leaf tendril respectively, let's analyze the definitions and examples of each type of tendril.

### Step-by-Step Solution:

1. **Understanding Tendrils**:
- Tendrils are specialized structures that help plants climb and support themselves. They can be classified into two types: stem tendrils and leaf tendrils.

2. **Identifying Stem Tendrils**:
- Stem tendrils are modified stems that arise from axillary buds. They are typically slender and spiral in shape, helping the plant to climb.
- Common examples of plants with stem tendrils include cucumber, pumpkin, and watermelon.

3. **Identifying Leaf Tendrils**:
- Leaf tendrils are modified leaves that serve a similar purpose of climbing. These tendrils can also be slender and coil around supports.
- A well-known example of a plant with leaf tendrils is the pea plant (Pisum sativum).

4. **Analyzing the Options**:
- **Option A**: Peas (leaf tendril) and cucumber (stem tendril).
- **Option B**: Acacia (not a tendril plant) and cucumber (stem tendril).
- **Option C**: Peas (leaf tendril) and Apuncia (not a common example).
- **Option D**: Cucumber (stem tendril) and peas (leaf tendril).

5. **Selecting the Correct Answer**:
- From the analysis, we see that option D correctly identifies cucumber as a stem tendril and peas as a leaf tendril.

### Final Answer:
The correct answer is **D. Cucumber and Peas**.
