(d) pteridophytes
Ans.)Option (a) algae

Explanation
Algae are classified as non-flowering plants. Algae plants have no flowers, stems, leaves, or rhizoids. Instead of these typical structures, algae consists of strands or individual cells. Generally displaying a green color due to their high content of chlorophyll (the substance in plants that assists in converting sunlight into energy), algae depend on photosynthesis and are seen covering wet areas such as rocks in streams and the surface of lakes. Algae feed marine life as well as animals that prey on marine life; algae is considered to be one of the most significant plants in existence because it forms the basis of the earth's healthy food chain, according to the Iowa State University Extension.
