An organ pipe is open at both ends. It is producing sound at its third harmonic, the frequency of which is \( 262 \mathrm{~Hz} \). The speed of sound is \( 343 \mathrm{~m} / \mathrm{s} \). What is the length of the pipe?
(A) \( 1.96 \mathrm{~m} \)
(B) \( 1.85 \mathrm{~m} \)
(C) \( 1.31 \mathrm{~m} \)
(D) \( 0.926 \mathrm{~m} \)
