D. Iris.

Answer

To solve the question "A plant in which fertilization occurs after the shedding of seed is," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a plant where fertilization happens after the seeds have been shed. This indicates a specific reproductive strategy.

2. **Identify the Options**: The options given are:
- A) Orchis
- B) Ginkgo
- C) Biscum
- D) Ais

3. **Recall Plant Types**: We need to consider the types of plants:
- Orchis is an orchid, which typically has a different reproductive strategy.
- Ginkgo is a gymnosperm, which has unique characteristics regarding seed and fertilization.
- Biscum and Ais do not have well-known reproductive strategies that fit the criteria.

4. **Focus on Ginkgo**: Ginkgo is a dioecious gymnosperm, meaning it has separate male and female plants.
- Female Ginkgo trees produce seeds, and after a period (about 4 months), the male trees produce pollen.
- The fertilization occurs after the seeds have been shed, which aligns with the question.

5. **Confirm the Answer**: Since Ginkgo is a gymnosperm where fertilization occurs after the shedding of seeds, it fits the criteria perfectly.

### Final Answer:
The correct answer is **B) Ginkgo**.
