Explanation:

Salesforce imposes strict governor limits to ensure efficient resource usage. In an environment with more than 2,000 lead records, an Apex transaction is likely to exceed the total number of records retrieved by SOQL queries, which is capped at 50,000 records per transaction.

Why Option C is Correct?

✅ SOQL queries in bulk transactions retrieve large data sets, potentially surpassing the record retrieval limit.
✅ If the query is not optimized, it might fetch more than the allowed number of records, triggering a limit error.
✅ Using pagination techniques or selective filters can help manage the retrieved record count efficiently.
