Best answer
Right choice is (d) Fluidity of pouring melt

For explanation: The mould material is basically selected on the considerations of the size of the casting, pouring temperature and the frequency of the casting cycle, which all together determine the total heat to be borne by the die. Fluidity of the pouring melt can be dependent on the shape of mould, but it is totally independent for the selection of moulding material.
