Answer :
The correct option is 1) Eroica. Beethoven's Symphony No. 3 in E-flat major, Op. 55, originally titled 'Bonaparte,' was later named 'Eroica' due to Beethoven's disappointment in Napoleon's actions.
The Beethoven symphony that was originally titled 'Bonaparte' but was later named 'Eroica' is his Symphony No. 3 in E-flat major, Op. 55. This shift in title was a direct result of Beethoven's disillusionment with Napoleon Bonaparte, whom he initially admired for his democratic and anti-monarchical views, but whom Beethoven then saw as betraying those ideals by declaring himself Emperor. Consequently, Beethoven tore off the title page of the score which bore the dedication to Napoleon, and eventually renamed the symphony 'Eroica,' implying the concept of a 'heroic' individual, rather than a specific person such as Napoleon. Hence, The correct option is 1) Eroica.
