What are isomers?

• In chemistry, when a molecule or compound has identical polyatomic ions or molecules then they are called isomers of that compound.
• This means that the number of atoms will be the same in each element or compound but the arrangement of atoms will be distinct in space.
• The phenomenon of the formation of different isomers is called isomerism. The physical and chemical properties of the isomers also change accordingly.

So, the correct option is A.
