The giant algae or sea weeds belong to class
The correct option is A Phaeophyceae
Seaweeds can be classified into three broad groups based on pigmentation: brown, red and green. Botanists refer to these broad groups as Phaeophyceae, Rhodophyceae and Chlorophyceae, respectively.
Brown seaweeds are usually large, and range from the giant kelp i.e., often 20 m long, to thick, leather-like seaweeds from 2-4 m long, to smaller species 30-60 cm long.
Red seaweeds are usually smaller, generally ranging from a few centimeters to about a meter in length; however, red seaweeds are not always red: they are sometimes purple, even brownish red, but they are still classified by botanists as Rhodophyceae, because of other characteristics.
Green seaweeds are also small, with a similar size range to the red seaweeds. Seaweeds are also called as macro-algae. This distinguishes them from micro-algae (Cyanophyceae), which are microscopic in size, often unicellular, and are best known by the blue-green algae, that sometimes bloom and contaminate rivers and streams.
