Final answer:
Angiosperms have pollen that can fertilize eggs without water, whereas gymnosperms lack this adaptive trait.
Step-by-step explanation:
Angiosperms have pollen that can fertilize eggs without water, which is an adaptive trait that gymnosperms lack. Gymnosperms, such as conifers, rely on wind for pollination, while angiosperms have developed the ability to use pollinators like insects and animals.
This adaptation gives angiosperms a reproductive advantage as they are not dependent on specific environmental conditions for pollination. The ability to reproduce efficiently in different habitats and climates has contributed to the success and diversity of angiosperms.
Therefore, the correct answer is B - Angiosperms have pollen that can fertilize eggs without water.
