Chance
The occurrence of events in the absence of any obvious intention or cause, often quantified as probability.

Final Answer :
A
Explanation :
Variability within groups is due to chance or random error, which is unexplained variation in the data that is not caused by the grouping factor or the level of the dependent variable. The F ratio is a statistical test that compares the variability between groups to the variability within groups, and it is used to determine if the grouping factor has a significant effect on the dependent variable.
