Answer:

Option A= Melting point of ice decrease as pressure increase

Explanation:

• Sledge, any freight- or passenger-carrying device that is dragged or pushed without the aid of wheels.
• Sledge consisting of two transversely connected wooden shafts dragged at an angle to the ground.
• A sledge is a land vehicle that slides across a surface, usually of ice or snow.
• It is built with either a smooth underside or a separate body supported by two or more smooth, relatively narrow, longitudinal runners similar in principle to skis. This reduces the amount of friction, which helps to carry heavy loads.
