B. Data outliers In this dataset, the income values vary widely, with Jessica Jones having a significantly higher yearly income compared to the others. This extreme value might be considered an outlier and could skew analysis if not addressed. The analyst might need to cleanse or process the data to handle this outlier, depending on the intended analysis. The other options do not apply here because: A. Data completeness: All entries are present for each row. C. Duplicate data: There are no duplicate entries. D. Missing values: No values are missing.
