Certain polymers have many start points as well as many end points. what are these polymers called?
a. linked polymers
b. linear polymers
c. branched polymers

The answer is c. Branched polymers.

Polymer is a large molecule formed by joining several monomers. The simplest polymers are linear polymers which have no branches. But, some polymers have many start point and end points known as branches, so those polymers are called branched polymers. They could be star polymers, brush polymers, comb polymers, etc.

The answer is observations and interpreting.
