- A) If i) and ii) only are correct
- B) If ii) and iii) only are correct
- C) If ii) and iv) only are correct

Did you know?
In the exam, you would be expected to have made a confirmed decision on an MCQ within 60 seconds.
It is also good exam technique to abstain if you are not sure on your answer.
