Answer: (A)

Data cleaning is crucial in analytics because it directly influences the accuracy and reliability of the insights generated from data. When datasets contain errors, such as duplicates, missing values, or incorrect entries, any analysis performed on that data may yield misleading or invalid results. By removing or correcting these errors through data cleaning, analysts can ensure that their findings are based on accurate and trustworthy information, which is essential for making informed business decisions.

This process helps maintain the integrity of the dataset, allowing organizations to derive meaningful conclusions and take actionable steps based on reliable analytics. Without proper data cleaning, the overall effectiveness of analytics is significantly compromised, emphasizing its critical role in ensuring high-quality outcomes in any analytical endeavor.
