Answer 1

Hint: The only living species in the Ginkgophyta division is ginkgo biloba, commonly known as ginkgo or gingko, also known as the maidenhair tree, and all others are extinct. With some fossils dating back 270 million years, it is a very ancient animal. These aquatic plants are generally referred to as watermeal or (mistakenly) duckweed, resembling specks of cornmeal floating on the water. Wolffia species, green or yellow-green, and without roots, are free-floating thalli.

Complete answer:
Peritrichous flagellation means that all directions (e.g., E. coli) have flagella projecting.
Gingko, a living fossil, is here. The newly discovered specimens, which formed over a hundred million years ago, are strikingly similar to the plants of today.
Selaginella has a rhizophore that is a prop like structure that originates at a branching point and, after making contact with the soil or a hard surface, forks dichotomously.
The Wolffia flower is the world's smallest known flower, measuring only 0.3 mm long. It has a single stamen and a single pistol.
The largest algae is Macrocystis, kelp (seaweed). The sporophyte, which is perennial and individuals persist for several years, is the stage of the life cycle that is commonly seen.

Additional Information: Coli (Escherichia coli) is a type of bacteria that is usually found in the gut. It is also present in the intestines of some species. Most of the E. categories Coli is safe and also helps maintain a balanced digestive tract. But if you ingest infected food or drink fouled water, some strains can cause diarrhea.
Selaginella is the only genus in the family Selaginellaceae, spikemosses, or lesser club mosses, of vascular plants. By having scale-leaves bearing a ligule and having spores of two kinds, this family is distinguished from Lycopodiaceae (the club mosses).
Macrocystis is a kelp genus which is monospecific. The largest of all Phaeophyceae, or brown algae, is included in this genus. At the base of its blades, Macrocystis has pneumatocysts.
So, the correct answer is ‘A-3, B-1, C-4, D-5, E-2’.

Note: A current taxon that closely resembles species otherwise known only from the fossil record is a living fossil. The fossil species must be old compared to the time of origin of the extant clade in order to be considered a living fossil. Living fossils are usually species-poor lineages, but they don't have to be.
