The answer to your question is D
Honestly would say A not sure
The answer is; D
The friction causes the ice at the base of the avalanche to melt into water (also due to the pressure of the weight of the ice-rock above). The melted water acts as a lubricant hence reducing the drag/friction in the avalanche movement. This increases its speed down the slope hence making it more destructive.
