The stave shows a treble clef with a whole note positioned on the fourth space, which corresponds to E in the treble clef. A flat accidental (♭) is placed immediately before the note, lowering it by a semitone to E flat (E♭).
The question asks which pitch sounds the same as the written note. This is an enharmonic equivalence question. On a piano or any equal-temperament instrument, E♭ and D♯ occupy the same key and produce the same frequency. Since D♯ is the enharmonic spelling of E♭, the pitch sounds the same as D (understood here as D♯, the sharp enharmonic).
Neither E, E flat (which is the note itself, not an enharmonic equivalent), nor D flat share the same pitch as E♭. D♯ (enharmonically D raised by a semitone) is the correct match.
