Final Answer :
A
Explanation :
ANOVA is an omnibus test, meaning it tests for an overall difference between the means of two or more groups without specifying which group(s) are significantly different. This is in contrast to post-hoc tests, which are performed after finding a significant result in an omnibus test to determine which specific groups are significantly different from each other.
