A tech company wanted to assess employee satisfaction with their new flexible work policy. They sent a survey link to all employees, but only 15% responded. The results showed overwhelmingly positive feedback. Which of the following is the most significant limitation of this study's findings?

✓ Correct Answer: Option C

A low response rate in a voluntary survey often leads to voluntary response bias. Individuals with strong opinions (either very positive or very negative) are more likely to respond, skewing results. Here, overwhelmingly positive feedback from a low response rate suggests those most satisfied were more likely to participate.
