• C. Sphagnum
• D. Polytrichum

Answer 1

The correct option is A

Spirulina

The correct option is A

Explanation of the correct option

1. Spirulina is the right choice because it contains calcium, niacin, potassium, magnesium, B vitamins, and proteins.
2. Spirulina is a richer source of protein with a 60 percent protein content.

Explanation of the incorrect option:

Option B:

Sargassum seaweed is a nutritious food rich in carotenoids, cellulose, protein, and aspartic and glutamic acids.

Option C:

Sphagnum is incorrect because it contains uronic acids, which readily exchange a hydrogen ion for a base cation in an aqueous solution.

Because the cells are dense with protoplasm and oil globules, Polytrichum is incorrect.

Final answer: Spirulina is a richer source of protein with a 60 percent protein content.
