  • Options
  • A. Error: Misplaced continue
  • B. Bye
  • C. No output
  • D. Hello Hi

  • Correct Answer
  • Error: Misplaced continue 

    Explanation
    The keyword continue cannot be used in switch case. It must be used in for or while or do while loop. If there is any looping statement in switch case then we can use continue.
