What should you avoid inside a loop?

Salesforce recommends that you avoid executing DML operations (such as Create or Update Records) or performing SOQL queries inside a loop. Doing so risks hitting governor limits and can significantly reduce flow performance.

Correct Option:

C. ✅ Executing record operations inside a loop should be avoided. Instead, use Assignment to build a collection variable and perform the DML outside the loop.

Incorrect Options:

A. Assigning variables inside loops is acceptable and often necessary.

B. Displaying data is not typical in a loop, but it’s not a best practice issue.

D. Nested loops are discouraged but not as critical as avoiding DML operations.

Reference Extract from Salesforce Developer Blog – Best Practices for Designing Efficient Flows:

“Avoid DML operations and SOQL queries inside loops. Use collections to handle record updates after the loop completes.”
