Solution

the probable structure will be C

as mass spectra shows no sign of Chlorine atom presence option B is ruled out

The option A, would give a base peak at 43 thus ruled out

Even the option D will follow -29 m/z pattern

and lastly, option E would give the base peak at 85 m/z, but rest of the fragments are not consistent with the spectra
