The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Adsorption**: The process being described is known as adsorption. This is a surface phenomenon where one substance (the adsorbate) adheres to the surface of another substance (the adsorbent). 2. **Identifying Components**: In the given scenario, the finely divided active carbon or clay acts as the adsorbent, while the dye in the dilute solution is the adsorbate. 3. **Process of Adsorption**: When the finely divided carbon or clay is stirred into the dye solution, the dye molecules are attracted to the surface of the carbon or clay particles. This attraction leads to the dye molecules being retained on the surface of the adsorbent. 4. **Resulting Effect**: As the dye molecules are adsorbed onto the surface of the carbon or clay, the concentration of dye molecules in the solution decreases. This results in a decrease in the intensity of color in the solution, making it appear lighter or faded. 5. **Conclusion**: Therefore, the decrease in color intensity of the dye solution is due to the adsorption of dye molecules onto the surface of the finely divided active carbon or clay.
