Solution

The correct option is D Rhodymenia and Porphyra.
Rhodymenia is a red alga and is well-known snack food. It has been an important source of dietary fibre throughout the centuries.
Porphyra is a cold water seaweed that grows in cold, shallow seawater. It has 30-35% proteins, 40-45% carbohydrates and a very high percentage of vitamins. The alga is sold and eaten together with rice.
So the correct answer is option D.
