The statement that is incorrect about John Adams is A. He is best known for his two operas, Nixon in China and Doctor Atomic. John Adams is not known for composing operas. He is actually a renowned American composer known for his minimalist and eclectic musical style. He won a Pulitzer Prize in music for a work commemorating those killed in the World Trade Center attacks and his father played a central role in his development as a composer.
