Answer

To solve the question "Pollination between flower of different plant of the same species is," we need to analyze the options provided and understand the definitions of the terms related to pollination.

### Step-by-step Solution:

1. **Understanding Pollination Types**:
- Pollination can be classified into self-pollination and cross-pollination.
- Self-pollination occurs when pollen from the same flower or another flower on the same plant fertilizes the ovule.
- Cross-pollination occurs when pollen from one plant fertilizes the ovule of a different plant.

2. **Analyzing the Options**:
- **(a) Xenogamy**: This term refers to cross-pollination between flowers of different plants of the same species. It involves the transfer of pollen from one plant to another.
- **(b) Geitonogamy**: This is a type of self-pollination where pollen from one flower fertilizes another flower on the same plant.
- **(c) Autogamy**: This refers to self-pollination within the same flower.
- **(d) Homogamy**: This term generally refers to flowers that are adapted for self-pollination but does not specifically denote cross-pollination.

3. **Identifying the Correct Answer**:
- Since the question specifies "pollination between flowers of different plants of the same species," the correct term is **Xenogamy** (option a), as it specifically describes the transfer of pollen between different plants of the same species.

4. **Conclusion**:
- Therefore, the correct answer to the question is **(a) Xenogamy**.
