Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Query only the specific fields needed rather than using SELECT *.
Why this is correct
Selecting only required fields reduces heap usage and improves performance.
- ✓
Avoid placing SOQL queries inside loops.
Why this is correct
Queries in loops easily exceed the 100 SOQL query limit.
- ✓
Use bind variables to parameterize query criteria.
Why this is correct
Bind variables optimize query execution and prevent injection.
- ✗
Execute a separate SOQL query for every child record individually.
Why it's wrong here
This violates bulkification and governor limits.
- ✗
Always use SELECT FIELDS(ALL) to ensure all data is retrieved.
Why it's wrong here
SELECT FIELDS(ALL) is restricted and generally inefficient for bulk Apex code.
