To solve this problem, we need to identify which row correctly categorizes gymnosperms and angiosperms.
### Definitions:
1. Gymnosperms: These are plants that do not produce flowers or fruits and typically have cones. Examples include conifers, cycads, and ginkgos.
2. Angiosperms: These are flowering plants that produce seeds enclosed within a fruit. Examples include flowering plants, grains, and fruit trees.
### Given Rows:
- Row A:
- Gymnosperms: Conifers, cycads, and gingkos
- Angiosperms: Flowering plants, grains, and fruit trees
- Row B:
- Gymnosperms: Grains, flowering plants, and gingkos
- Angiosperms: Fruit trees, conifers, and cycads
- Row C:
- Gymnosperms: Fruit trees, cycads, and grains
- Angiosperms: Conifers, gingkos, and flowering plants
- Row D:
- Gymnosperms: Conifers, cycads, and gingkos
- Angiosperms: Flowering plants, grains, and fruit trees
### Analysis:
- Row A: Correctly categorizes gymnosperms (conifers, cycads, gingkos) and angiosperms (flowering plants, grains, fruit trees).
- Row B: Incorrectly categorizes grains and flowering plants as gymnosperms, but they are actually angiosperms.
- Row C: Incorrectly categorizes fruit trees and grains as gymnosperms, but they are actually angiosperms.
- Row D: Correctly categorizes gymnosperms (conifers, cycads, gingkos) and angiosperms (flowering plants, grains, fruit trees).
### Conclusion:
Both Row A and Row D correctly categorize the plants into gymnosperms and angiosperms. Given the format of the question, where only one correct answer is expected, the answer to the problem is:
A
