• B. Brown algae
• C. Red algae
• D. Golden brown algae

Answer 1

The correct option is B Brown algae

• The large (giant) parenchymatous forms of brown algae are called kelps or sea weed or trees of seas or forest of sea. (e.g., Maccrocystic 30-60m; Nereocystis 20-30m, Laminaria 2-12m).
• Both contain fucoxanthin, which is brown in colour. Due to which both are grouped under brown algae.
• Hence option B is the correct option.
