Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Check the connection status after every query.
Why it's wrong here
This is inefficient and does not handle runtime errors.

Check the return value of the execute() method.
Why it's wrong here
execute() returns a cursor object, not an error status.
- ✗
The library crashes the program automatically.
Why it's wrong here
Python provides exception handling for this purpose.
- ✓
Use a try-except block to catch sqlite3.Error.
Why this is correct
sqlite3 raises specific exceptions for database errors.
