The answer is option “c”. see it was boiling water, she poured first into container “a” so it will be having the highest temperature than she poured to container b than to c and finally to container d so during this experiment the boiling water goes to lowest temperature and the last container was container d . So container a will be having the highest temperature and container d will be having the lowest temperature.
