Correct answer is D
Isomers have the same molecular structures(but different structures). so whatever the structures are, they must contain the same amount of carbon, the same amount of hydrogen, and the same amount of oxygen as in this case. Just count the number of hydrogens (including the hydrogen in OH). you should get 10 hydrogens from A, B, C, and E. in total, you should have C4H10O. options A, B, C, and E have this in common. but the option D has only C4H8O.
