Which combination of musical instruments is most suitable for a string quartet?
a.
a woodwind, two pianos, and a violin
b.
two violins, a viola, and a cello
c.
a piano, a horn, and a bassoon
d.
a cello, two violas, and a clarinet

The answer would be b, two violins, a viola, and a cello. the definition of a string quartet is a group of 4 musicians playing string instruments. all of the other answers would be wrong because they contain other instruments besides string instruments, like piano, horn, woodwind, and clarinet. i hope this helps! :D
