When a difference between two groups is statistically significant, it means that the likelihood of obtaining that difference by chance is very low, typically less than 5% (p < 0.05). In other words, the observed difference is most likely due to a real effect rather than sampling error or chance. Therefore, the correct answer is C - statistically significant.
