D. a and b

Answer

To solve the question regarding the inflorescence with two types of centripetally arranged sessile flowers with hair-like sepals, we need to analyze the provided options and determine which one is not associated with this type of inflorescence.

### Step-by-Step Solution:

1. **Understanding the Inflorescence**:
- The question describes an inflorescence that has two types of centripetally arranged sessile flowers with hair-like sepals. This indicates a specific floral arrangement.

2. **Analyzing Each Option**:
- **(a) Nectar glands at the base of the corolla**:
- Nectar glands are often present in flowers to attract pollinators. This feature is typically associated with many types of flowers, including those with sessile arrangements. Therefore, this option is associated with the inflorescence.

- **(b) Axile placentation**:
- Axile placentation refers to the arrangement of ovules in a compound ovary, where ovules are attached to the central axis. This type of placentation is not typically associated with the described inflorescence. Hence, this option is likely not associated.

- **(c) Superior ovary**:
- A superior ovary is one where the ovary is positioned above the other floral parts. While this can occur in some flowers, it is not a defining feature of the inflorescence described. Thus, this option may also not be associated.

- **(d) Scaly bracts**:
- Scaly bracts are often present in certain types of inflorescences, providing support and protection to the flowers. This feature is associated with the described inflorescence.

3. **Conclusion**:
- After analyzing all the options, we find that both **(b) Axile placentation** and **(c) Superior ovary** are not associated with the described inflorescence. Therefore, the correct answer to the question is **(b) Axile placentation**.

### Final Answer:
**(b) Axile placentation**
