Correct option is
D

All of the above.

We know that ice is solid form of water which is at 0C . And all other forms given in question are liquid forms and all liquid forms are above melting point of water that is 0C. So compared to ice all beakers are comparatively at higher temperature and will give sensation of warmth to our hand when we put our hand in any of these beakers after putting it in ice because they are at higher temperature than ice.
