Best answer
Right option is (a) Fluidity

Explanation: Fluidity is the property of molten metal, which is used to describe the capability of the molten metal to fill mould cavities. Solidification interval, viscosity and surface tension are the factors which help in determining the fluidity of the molten metal.
