Final answer:
The incorrect statement about Lully is that he wrote more than 450 concertos, as this achievement is attributed to Antonio Vivaldi, not Lully. Option b is correct.
Step-by-step explanation:
All of the statements about Lully are correct with the exception of: 'b. writing more than 450 concertos, he was the most influential and prolific composer of the Baroque concerto.' This statement is incorrect because Jean-Baptiste Lully did not write more than 450 concertos; instead, it was Antonio Vivaldi, an Italian Baroque composer, who was known for his numerous concertos.
Lully was a French composer of the Baroque era who did create a highly disciplined orchestra, was appointed superintendent of court music by Louis XIV, perfected the French overture, and, indeed, met his demise due to a conducting accident.
