Answer:E is as far from C as it is from D. So,CE = E-C = (-1-5,0-2) = (-6,-2)So, add that much to E and you getD = E+(E-C) = (-1,0)+(-6,-2) = (-7,-2)

D. This is because artificial selection is basically the human breeding of plants or animals, and we do so in a way to bring forth the best traits to solve a problem or create a better product.

The plant contains vascular tissue and has an alternation of generation. But, it lacks seeds. So, the plant is a Pteridophyte.
- Vascular tissues are absent in thallophytes and bryophytes. They are found in pteridophytes, gymnosperms and angiosperms.
- The sporophyte and gametophyte generation is common in bryophytes and pteridophytes.
- Seeds are produced in plants that come under the group gymnosperms and angiosperms. The presence of seeds is the main characteristic of these groups.
- Thallophytes, bryophytes and pteridophytes lack seeds. The reproduction in plants that comes under these groups occurs with the help of spores.
Thus, the recently discovered species of the plant should be classified based on the presence of vascular tissues, gametophytes and sporophytes. As pteridophytes contain vascular tissues, sporophytes and gametophytes and lack seeds, the plant is a pteridophyte
