A large group of people who play brass, woodwind, and percussion instruments, with no strings.

• A. Concert band
• B. Rock band
• C. Jazz combo
• D. Orchestra

Answer: (A)

Ensembles are grouped by instrument families, and a large group that plays brass, woodwinds, and percussion with no string instruments fits a concert band. This type of ensemble focuses on wind sections—brass and woodwinds—plus percussion, producing a broad, blended sound suitable for marches, patriotic pieces, and wind-band repertoire. In contrast, a rock band centers on guitars and bass (strings) with drums, so strings are present; a jazz combo is typically smaller and often centers around a rhythm section with a horn lineup but not a large wind-and-percussion ensemble; and an orchestra includes a full string section (violins, violas, cellos, basses) alongside winds, brass, and percussion. The description given matches a concert band most closely.
