Answer 1

The correct option is B Brown algae

Laminaria (Kelp) and Fucus (Rock Weed) are examples of Brown algae. It is a type of seaweed that is native to Japan. It contains iodine, an element that the body needs to make thyroid hormones. Laminaria species can form vast, forestlike kelp beds and provide habitat for many types of fish and invertebrates. It is also a rich source of iron and potassium. Despite serious safety concerns about laminaria, some people use laminaria as medicine.

Fucus is a genus of brown algae found in the intertidal zones of rocky seashores almost throughout the world. It is, also called rockweed, a genus of brown algae, common on rocky seacoasts and in salt marshes of northern temperate regions. Adaptations to its environment include bladderlike floats (pneumatocysts), disk-shaped holdfasts for clinging to rocks, and mucilage-covered blades that resist desiccation and temperature changes.

So, the correct answer is option B.
