```Given the stack trace, which statement is true about the exception handling?
⚠ Common exam trap
Test-takers frequently confuse the 'must handle or declare' rule for checked exceptions with the idea that unchecked exceptions cannot be caught at all, leading them to incorrectly select Option D.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The SQLException is a checked exception, and the code must handle it or declare it.
SQLException is a checked exception (a subclass of Exception but not RuntimeException), so the Java compiler enforces that it must be either caught in a try-catch block or declared in the throws clause of the enclosing method. The stack trace indicates that an SQLException occurred, and the code must handle this checked exception to compile successfully.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Both exceptions are checked, and the code must handle both.
Why it's wrong here
Only SQLException is checked; RuntimeException is unchecked.
- ✗
The RuntimeException is caused by a checked exception, so it must be declared in the throws clause.
Why it's wrong here
RuntimeException is unchecked; it does not need to be declared. The cause being checked does not require declaration of the wrapper.
- ✓
The SQLException is a checked exception, and the code must handle it or declare it.
Why this is correct
SQLException is checked and must be handled or declared.
- ✗
The RuntimeException is an unchecked exception, so it cannot be caught.
Why it's wrong here
Unchecked exceptions can be caught; they are not required to be handled but can be.
