d. Matter is composed of time particles called molecules

Answer 1

(C) is incorrect. Molecules can be as small as an H2 molecule or a million times bigger, such as a protein (called a macromolecule)

I assume in (d), you meant to say "tiny", not "time".

C & D are incorrect, A is usally correct

C - Molecules come in many sizes

A is incorrect at a temperature of absolute zero

Answer 3

Choice "C. All molecules have the same size and mass" is not correct. Molecules are made up of different atoms. Every atom has a different atom size and a different atomic mass. Therefore, different molecules differ in their size and mass.
