Best answer
The correct answer is (d) amylopectin; C1-C6

The best explanation: Amylopectin is the water insoluble branched constituent of starch which makes up 80-85% of its structure. It consists of straight chains of glucose through C1-C4 linkage, with the C1 of the terminal glucose of each chain linking with the C6 of another glucose unit in the next chain.
