Hint :We know that the isomers are molecules with the same molecular formula but have different arrangement of atoms and molecules. Isomers can be split into broad group’s mainly structural isomers and stereoisomers. The compounds showing isomerism are known as isomers.

Complete Step By Step Answer:
Molecules that have the same molecular formula but different molecular structure. Our question is related to functional isomers (structural isomers that have the same molecular formula but with the atoms connected in different ways and therefore falling into different categories. Ethanol, Acetic acid, Dimethyl ether and dimethyl ether are classes of organic compounds in one which contain carbon and hydrogen. They have different functional groups attached to it in ethanol as a functional group, in acetic acid as a function ground and in dimethyl ether and diethyl ether they contain ester functional groups.
We know that isomerism is the phenomenon in which two or more compounds have the same chemical formula but different structures. There are different structures. Functional isomers have the same molecular formula but different functional groups. Hence dimethyl ether and ethyl alcohol are the functional isomers of each other.
Dimethyl ether is an organic compound; it is a colorless gas that is a useful precursor to other organic compounds and an aerosol propellant that is currently being demonstrated for use in a variety of fuel applications. It is an isomer of ethanol Diethyl Ether or simple ether is an organic compound. It is a colorless, highly volatile, sweet-smelling flammable liquid.
Therefore, correct answer is option C.

Note :
Remember that the Functional group isomers have the same molecular formula but different functional group. Functional group is one which is a group of atoms whose. Identical functional groups tend to have similar properties. There are different types of isomers, such as, position isomers, tautomers, chain isomers etc.
