Answer

Explanation:

Step1: Identify relevant values

The number of adults taking the supplement and having a cold is 108, and the total number of adults is 506.

Step2: Calculate the percentage

The formula for percentage is $\frac{\text{Part}}{\text{Total}}\times100%$. So, $\frac{108}{506}\times 100%\approx 21.34% \approx 21%$.

Answer:

B. 21%
