• D. Miles Davis

Answer: (B)

Think about how jazz expanded from improvised solos into large, color-filled ensembles. Duke Ellington stands out because he built a career as a master composer and bandleader who shaped the sound of jazz through orchestration and long-form pieces. He led one of the most influential big bands of the swing era, writing music that was tailored to the strengths of individual players and explored rich harmonies, inventive timbres, and thematic development across extended performances. His arrangements treated the orchestra as a palette of colors and moods, elevating jazz from simple dance music to a sophisticated art form and shaping its direction for decades. While other figures also transformed jazz—pioneering bebop or pushing modern, modal approaches—their impact centers more on improvisation and stylistic shifts, whereas Ellington’s lasting contribution lies in the grand, composed voice he brought to jazz. That is why Duke Ellington is the best fit.
