ANSWER

OPTION C

EXPLANATION

Firstly, we need to define the term matter

Matter is anything that mass and occupies space. Matter exists in three states which are; Liquid, solid, and gas.

From the diagram given, you can see that, there is a change state from solid to liquid

In the solid-state of matter, the particles are closely packed together because of the strong electrostatic force holding the particles together. So, when the solid substance is heated the particles vibrate about a fixed position because the bond holding the particles together has not been broken. on further heating, the particles start to move freely and move independently of each other. At this point, a change of state from solid to liquid has occurred.

Therefore, to determine the change of the molecule, the best question to ask is what is the position of relative to each other
