The appropriate answer is e. gymnosperm. Gymnosperms have seeds that are not protected by an ovary or fruit. A popular example of a gymnosperm are conifers. Another characteristic of gymnosperms is that they do not have bright flowers. The Greek word for gymnosperm literally translates to naked fruit. The seeds of these plants are open to the air and as such they are directly pollinated by the wind.
