(A) digitizing and analyzing the sound emissions on computers, a team of scientists found the noise not
(B) digitizing and analyzing the sound emissions on computers, a team of scientists found that the noise was not

(D) the sound emissions were digitized and analyzed on computers, a team of scientists found that the noise was not
