Yes you are right as from the phase diagram it can be seen :

A. Substance X is in the solid phase in the area shown by “1”.

B. Substance X exists as a solid, a liquid and a gas at point D.

D. Substance X is a liquid in the area shown by "2"

But the point C is not correct as Substance X is not undergoing a change from a liquid to a gas at the line shown by E while it undergoes a phase change from solid to gas.

⇒The composition , decomposition or displacement of molecules of matter during chemical change is called chemical reaction.

▪️ $\underline{ \bold{ \sf{ \purple{ \: Further \: more \: explanation}}}}$

Various conditions bring about these changes. The chemical reactions are represented by chemicalequation. The compounds or elements that take part in chemical reaction are called reactant. They are written at the left side of an arrow that represent a change while the compound or elements that formed after the chemical change are called product. They are written at the right side of the arrow.

▪️ $\underline{ \bold{ \sf{ \purple{For \: example}}}}$
