A range expressing estimated uncertainty.
Brief rationale: A confidence interval gives an estimated range of values (from sample data) within which the true population parameter is likely to lie, reflecting uncertainty. The other options describe different concepts (likelihood of sample → not CI; power → probability of detecting effect; maximum difference → not accurate).
