Which statement best explains how the structure of a starch molecule relates to its function?
1.A branching structure makes the molecule stronger.
2.A branching structure contains bonds that are harder to break.
3.A branching structure provides many points where enzyme digestion can take place and release glucose molecules.

The correct option is 3.
Starch is a long chain polymer which can be broken down into glucose units. The starch polymer is made up of many branches, these branches serve as the digestion sites, where enzymes can attach and catalyze the breaking down of starch into glucose units for use inside the cells.
