Answer:
Correct Answer: C
Solution:
- Amylose and Amylopectin are polymers of $ \alpha - $ D-glucose, so $ \beta $ -link is not possible. Amylose is linear with 1 $ \to $ 4 $ \alpha $ -linkage whereas Amylopectin is branched and has both 1 $ \to $ 4 and 1 $ \to $ 6 $ \alpha $ -linkages. So option [c] should be the correct option.
