Which of the following would be a risk practitioner's GREATEST concern related to the monitoring of key risk indicators (KRIs)?

Retaining logs for longer than required is a compliance and data retention issue, but it does not directly compromise the integrity or accuracy of the KRI data being analyzed.

Reviewing logs annually means the KRI monitoring is not timely or frequent enough, but it does not inherently corrupt the accuracy of the data itself if it were to be analyzed.

Storing logs in a multi-tenant cloud environment poses security and privacy risks if not properly secured, but it doesn't automatically mean the logs are modified before analysis, assuming proper controls are in place.

If logs, which often serve as the data source for KRIs, are modified before analysis, their integrity is compromised, making the Key Risk Indicators inaccurate and unreliable for informed decision-making.
