Solution
The correct option is D Cycads
The cycads are a small group of plants with many unique features. Cycad plants are dioecious (i.e., male and female reproductive structures are borne on separate plants) and reproduction is by seeds, which are produced on open carpophylls or seed-bearing leaves. The coralloid roots of cycads are also characteristics not seen in other seed plants and the cycads lack the axillary buds seen in other seed plants.Therefore, the correct answer is option D.
