Solution

The correct option is D All X, Y, and Z
We know that ice is a solid form of water that is at 0° C. And all other forms given in the question are liquid forms and all liquid forms are above the melting point of ice which is 0° C.
So, compared to ice, all beakers are comparatively at higher temperature and will give the sensation of warmth to our hand when we put our hand in any of these beakers after putting it in ice.
