a rootless plant
Answer is Wrong!
Answer is Right!
The correct answer is (b), an aquatic plant.
A hydrophyte is a plant that grows in water, either fully submerged or with its roots in the mud. They have adapted to living in water by having special features such as large, thin leaves that allow them to absorb oxygen from the water. Some common examples of hydrophytes include water lilies, cattails, and water hyacinths.
(a) is incorrect because a marine animal is an animal that lives in the ocean.
(c) is incorrect because a plant disease is a disease that affects plants.
(d) is incorrect because a rootless plant is a plant that does not have roots.
