- Amylase: A plant polysaccharide with \( \alpha \)-1,4 and \( \alpha \)-1,6 glucose linkages, identified as \( \alpha \)-C1-C4 plant (IV).
- Cellulose: A plant polysaccharide with \( \beta \)-1,4 linkages, identified as \( \beta \)-C1-C4 plant (I).
- Glycogen: An animal polysaccharide with \( \alpha \)-1,4 and \( \alpha \)-1,6 glucose linkages, identified as \( \alpha \)-C1-C4 \( \alpha \)-C1-C6 plant (III).
- Amylopectin: A plant polysaccharide similar to glycogen, containing \( \alpha \)-1,4 and \( \alpha \)-1,6 linkages, identified as \( \alpha \)-C1-C4 plant (II). Therefore, the correct answer is (2).
