Options

A. Insects which helps in pollination
B. Insects consume pollen without bringing
C. Bees which helps in pollination
D. Brids which helps in pollination

Answer

**Step-by-Step Solution:**

1. **Understanding Pollen Robbers**: Pollen robbers are organisms that interact with flowering plants but do not contribute to the process of pollination. Instead, they consume the pollen grains without transferring them to other flowers.

2. **Analyzing the Options**: The question provides several options regarding who or what pollen robbers are. We need to evaluate each option to determine which one fits the definition of pollen robbers.

3. **Evaluating the First Option**: The first option mentions "insects which help in pollination." Since these insects facilitate the transfer of pollen from one flower to another, they are not pollen robbers. This option is incorrect.

4. **Evaluating the Second Option**: The second option states "insects that consume pollen without bringing." This description aligns with the definition of pollen robbers, as these insects do not contribute to the pollination process. This option is correct.

5. **Evaluating the Third Option**: The third option refers to "bees which help in pollination." Like the first option, bees are known for their role in pollination and do not fit the definition of pollen robbers. This option is incorrect.

6. **Evaluating the Fourth Option**: The fourth option mentions "birds which help in pollination." Similar to bees and other pollinating insects, birds that assist in pollination are not considered pollen robbers. This option is also incorrect.

7. **Evaluating the Fifth Option**: The fifth option refers to "ornithophyllae," which is a term related to plants that are pollinated by birds. Since this involves successful pollination, it does not represent pollen robbers. This option is incorrect as well.

8. **Conclusion**: After evaluating all the options, the correct answer is the second option: "insects that consume pollen without bringing." These insects are the true pollen robbers as they do not contribute to pollination.

**Final Answer**: Insects that consume pollen without bringing.
