Verified by Toppr

The correct option is A not freeze into ice
A test tube containing water which is surrounded by melting ice cannot freeze into ice because first of all after sometime both water and melting ice will come at 0oC. And while water is converted into ice, it releases heat and there is nothing which can absorb latent heat of fusion which is released by freezing water.
