A 0.25-m string, vibrating in its sixth harmonic, excites a 0.96-m pipe that is open at both ends into its second overtone resonance. The speed of sound in air is 345 m/s. The common resonant frequency of the string and the pipe is closest to
 
  A) 540 Hz.
  B) 360 Hz.
  C) 450 Hz.
  D) 630 Hz.
  E) 700 Hz.
