B. Beethoven

Explanation:

     Ludwig van Beethoven (1770-1827) is considered the greatest and most influential composer of classical music of all time, alongside Bach and Mozart. One of his most famous works is the 9th Symphony, which is still played today. In addition, he was responsible for creating the romantic style with the 3rd Symphony and the 4th and 5th Concerto for Pianos.

    One of the curious facts associated with the composer is deafness. The disability started to manifest when he was just 26 years old and, despite never having completely lost his hearing.

    The fact created difficulties for Beethoven which, together with other complications in his personal life, resulted in some years of little relevant production. For example, he composed one of his most famous works, the 9th Symphony, after losing his hearing.
