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
✓
return
Options A (return) and D (break) are correct. The return statement terminates the enclosing method, thereby ending the loop. The break statement directly terminates the innermost loop. Option B (exit) is not a Java statement; System.exit() is a method but it is not a control flow statement for loop termination. Option C (System.gc()) is a garbage collection hint and does not affect loop control. Option E (continue) skips the current iteration but does not terminate the loop.
