Cohesion is the clinking of ______ molecules.

different
unlike
like
mixed

The correct answer is: like

Cohesion is the clinking or attraction between similar molecules, specifically of the same substance. Option A, different, and option B, unlike, refer to molecules of different substances, which do not exhibit cohesion. Option D, mixed, also does not accurately describe the clinking of molecules, as it suggests a combination of different substances rather than similar molecules. This behavior of cohesion can only occur between molecules of the same substance due to their similar structures and chemical properties.
