Explanation

The proper sequence in a UV/visible spectrophotometer starts with the light source, followed by the sample cell where the sample is analyzed. Next, the detector captures the transmitted light, then the monochromator selects the desired wavelength, and finally, the results are shown on the display. Therefore, option B correctly represents this order.
