The right answer is B.
Starch is, along with cellulose, the most common polysaccharide in the plant world. It constitutes the essential energy reserves of plants and is a component of the diet of humans. It is part of the group of slow sugars. Its consumption is particularly recommended to those who practice a sport.
Glycogen, which is a polysaccharide, is the form in which carbohydrates are stored in the body (animals and fungi). Glycogen is broken down into glucose molecules when the body needs energy.
DNA needs to replicate before cells divide to give the complete set of genetic instructions to its daughter cells, (or ensures that each new cell inherits all of the genetic traits of the parent cell).
Hope this helps! :D
