D. Intercalary.

Answer

To solve the question about the arrangement of conidia in Albugo, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Albugo**:
- Albugo is a genus that belongs to the family Albuginaceae. It is classified as an oomycete, which means it is not a true fungus but a plant parasite.

2. **Identifying Conidia**:
- Conidia are asexual spores produced by fungi and some related organisms. In the case of Albugo, they are involved in the reproduction of this organism.

3. **Arrangement of Conidia**:
- The question asks about the arrangement of conidia in Albugo. The options given are irregularly, acropetally, basipetally, and intercalary.

4. **Analyzing the Arrangement**:
- The transcript mentions that the conidia of Albugo show a parallel arrangement. This means that they are organized in a specific pattern.
- It is noted that the arrangement consists of younger conidia at the base and older conidia at the top. This indicates a succession in the arrangement.

5. **Determining the Correct Arrangement**:
- The arrangement described (younger at the bottom and older at the top) corresponds to a basipetal pattern, where the older structures are positioned at the top, and the newer ones are at the base.
- Therefore, the correct answer to the question is that the conidia of Albugo are arranged basipetally.

### Final Answer:
The conidia of Albugo are arranged **basipetally**.
