Answer:
C. The ancestor lacked both seeds and flowers, because these traits evolved later in the evolutionary lineages of cone-bearing plants and
flowering plants
Explanation:
<u>The most accurate description of the common ancestor of cone-bearing and flowering plants would be that the ancestors lack both seeds and flowers because these traits evolved later in the evolutionary lineages of cone-bearing and flowering plants.</u>
According to the cladogram, the common ancestors to both cone-bearing and flowering plants is mosses and ferns. Embryo evolved in mosses but there are no vascular tissues, seeds, and flowers. Advancement occur in ferns with the development of vascular tissues in addition to embryo but still, there is no seeds neither flowers.
The evolution of seeds only started in cone-bearing plants in addition to embryo and vascular tissues while the development of flowers in addition to the rest of the features is only found in flowering plants.
Hence, the correct option is C.
True. They have tools to do so.
