Ascientist discovers a new type of polymer. what must be true about this polymer? a. it contains carbon atoms arranged in a ring structure. b. it has double bonds between all the carbon atoms. c. it contains molecules of many different types. d. it is made of large molecules with repeating units.

Option (D) is the correct answer.

Explanation:

A polymer is a large molecule which contains repeating units.

A polymer forms long chain of atoms which are not necessarily arranged in a ring structure. There are not only double bonds between all the carbon atoms, as there can be single bonds or triple bonds between the atoms of a polymer.

A polymer does not contain many different type of molecules as there are many repeating units and not many molecules in a polymer.

A polymer is made of large molecules with repeating units.

Thus, we can conclude that option (D) is the correct answer.
