The anthem of the European Union is 'Ode to Joy' from Beethoven's Symphony No. 9 (the 'Choral' Symphony), adopted in 1985. Option A incorrectly references Symphony No. 3 (the 'Eroica', not 'Erotica'). Option B is Mozart's work, not the EU anthem. Option D references 'The Song of Marseille' which appears to be a garbled reference to the French national anthem 'La Marseillaise'.
