When two pieces of ice are pressed together, they stick together because the increased pressure lowers the melting point of ice at the point of contact. This allows a thin layer of ice to melt, creating a temporary liquid bridge between the pieces, which refreezes upon release of pressure, binding the pieces together.

When two pieces of ice are pressed together, they stick together because the increased pressure lowers the melting point of ice at the point of contact. This phenomenon allows a thin layer of ice to melt, creating a temporary liquid bridge between the pieces. Upon release of pressure, this liquid refreezes, binding the pieces together. Therefore, the correct answer is [A] Due to increase in pressure the melting point of ice decreases. Understanding this effect is fundamental in various applications, including ice sculpting, construction, and geology.
