Answer

To solve the question "Pollination occurring in closed flowers is", we need to analyze the given options and understand the definitions of each term.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks about the type of pollination that occurs in closed flowers.

2. **Analyzing the Options**:
- **Allogamy**: This term refers to cross-pollination, where pollen is transferred from the anther of one flower to the stigma of another flower. This is not applicable to closed flowers.
- **Clistogamy**: This term describes a type of pollination that occurs in closed flowers. In clistogamous flowers, the flowers do not open, and self-pollination occurs because the anthers and stigma are in close proximity.
- **Decliny**: This term is not commonly associated with pollination and refers to the presence of only one kind of reproductive structure in a flower. This does not apply to the question.
- **Protogamy**: This term refers to a condition where the female reproductive part (pistil) matures before the male part (anther) to prevent self-fertilization. This is also not applicable to closed flowers.

3. **Identifying the Correct Answer**: Based on the definitions, clistogamy is the correct term for pollination occurring in closed flowers, as it involves self-pollination in flowers that do not open.

4. **Conclusion**: The correct answer to the question is **Clistogamy**.

### Final Answer:
The correct option is **Clistogamy**.
