Universal1 Containers (UC) is a non-profit organization with more than 20,000,000 members (donors).

Account Data Skew: Data skew occurs when a single user owns a disproportionately large number of records (e.g., more than 10,000). This can cause performance degradation due to sharing recalculations and record locking during updates.

Why Option A is Correct:

With each donation rep owning over 50,000 records, performance issues arise due to ownership-based sharing recalculations and potential lock contention.

Addressing this requires redistributing ownership or using features like queues or groups to mitigate skew.

Why Others Are Incorrect:

Option B: Access configuration is not directly related to performance degradation in this context.

Option C: Sharing recalculation is a symptom, not the root cause.
