Answer:
e) All plants produce seeds.
Explanation:
The seed-producing plants are grouped as spermatophytes. Spermatophytes include only angiosperms and gymnosperms as both of these groups of plants produce seeds. Some of the examples of seed producing plants are mango, sunflower, etc.
Other plant groups such as bryophytes, pteridophytes do not produce seeds for reproduction. Sphagnum (moss), Adiantum (fern), etc, do not produce seeds.
