Answer:  

C. The differences between the observed and expected counts are too large to be attributed to chance.

Explanation:

The p-value of the statistic represents the chance that the observed count is based on luck or chance. When p value too high, the research can't be used since the chance that its not represent real condition are too high. Most researchers use 5% (0.05) as the cutoff of something called statistically significant. In this research, the p-value is 0.04 or 4%, so it is statistically significant.
