 Options:  <1> It is inversely proportional to the variance (standard deviation of the band). <2> It is directly proportional to the number of theoretical plates and inversely proportional to the length of the column. <3> It is directly proportional to the variance and inversely proportional to the distance traveled by the center of the band to the detector (L). <4> It is directly proportional to the variance and distance traveled by the center of the band to the detector (L). <5> It does not depend on the variance or the distance traveled by the center of the band.
Output (English): 3
