Final answer:
Johann Sebastian Bach composed music during the period of 1716-1721, a time which aligns perfectly with his completion of the Brandenburg Concertos. The other composers listed were either also active during this period but not specified within the exact years or, in the case of Mozart, were not yet born.The correct option is D.
Step-by-step explanation:
The composer who composed a piece around 1716-1721 is Johann Sebastian Bach. During this period, Bach was actively composing music, and it was the era of the Baroque period, not the Romantic era.
Notable works from this time include Bach's Brandenburg Concertos, which were completed in 1721.
The timeline does not fit the other composers listed: Antonio Vivaldi and George Frideric Handel were also composing during the baroque period, but the question specifically asks for works composed between 1716-1721, where Bach's activities are well-documented.
Wolfgang Amadeus Mozart, on the other hand, was not even born until 1756, making him an improbable choice as he belongs to a later period, the Classical era, which preceded the Romantic era.The correct option is D.
