Algae live in bodies of water and damp places and are commonly found in both aquatic and terrestrial environments. Terrestrial algae mostly live in moist, tropical areas. They prefer wet places, because they do not have vascular tissues and the other necessary adaptations to survive on land.
        
             
        
        
        
Carbon atoms have 4 valence electrons. That allows them to make 4 covalent bonds. That means they can make really big molecules. All the organic molecules have Carbon in them.
        
             
        
        
        
Answer:
Here the fucose is linked to galactose by alpha1,2 glycosidic linkage.
Explanation:
Fucose is a deoxy sugar consist of 6 carbon atoms which means fucose is a hexose sugar.
    Fucose does not contain -OH group at C6 carbon that"s why it is termed as deoxy sugar.
      Fucose can link to both Nactylglucosame by alpha-1,6 glycosidic linkage and to galactose by alpha-1, glycosidic linkage  generates the H antigen.
    As donor is blood type B that means fucose is linked to galactoseof H antigen by alpha 1,2glycisidic linkage.
 
        
             
        
        
        
Ok, I'm not fully sure but answer B sound right, so I think it's right
