One string on a guitar is exactly in tune . The guitarist uses this string to produce a tone with a frequency of 196 Hz by pressing down at the proper fret . An adjacent string can also be used to produce this tone without being pressed against a fret . However , this adjacent string is out of tune and produces a tone that sounds lower in frequency than the other tone . When the tones are produced simultaneously , the beat frequency is 5.0 Hz . What frequency does the adjacent string produce ?

a) 196 Hz

b) 191 Hz

c) 171 Hz

d) 201 Hz

e) 186 Hz
