112. Solving a chemistry problem

54. The spectrophotometer has two scales - light transmission in optical density. At a certain wavelength, the light transmission of three solutions was measured. Using the data below, calculate the optical density for the same solutions.
At which of the obtained values of optical density (indicate the number of the solution) will the relative systematic error of the photometric determination be the smallest?
Option Light transmission Т, %
