A

Add alkaline copper solution to the protein sample → Allow reaction to occur → Measure absorbance at a specific wavelength → Calculate protein concentration

B

Measure absorbance at a specific wavelength → Add alkaline copper solution to the protein sample → Calculate protein concentration → Allow reaction to occur

C

Allow reaction to occur → Measure absorbance at a specific wavelength → Add alkaline copper solution to the protein sample → Calculate protein concentration

D

Calculate protein concentration → Add alkaline copper solution to the protein sample → Allow reaction to occur → Measure absorbance at a specific wavelength

Understanding the Answer

Let's break down why this is correct

First you add the alkaline copper solution to the protein sample. Other options are incorrect because This answer puts measuring before the reaction; It says let the reaction happen first, then measure, then add solution.
