Graphs of the first four standing waves in a closed organ pipe are shown in this figure. If the organ pipe were closed at both ends, how would the pattern of harmonics differ from the situation depicted in the figure?

a. All the harmonics occur when the organ pipe is closed at both ends.
b. The same occurs as shown in the figure, i.e., the even harmonics are missing.
c. The same occurs as shown in the figure, i.e., the odd harmonics are missing.
