Solution

The correct option is B making an amalgam
The reaction of sodium with water is highly exothermic. However, the rate of the reaction can be lowered by making an amalgam. When sodium amalgam is formed, the rate of reaction with water is lowered because the surface area of sodium that can come in contact with water decreases.
