Hint: We know that the metals are made up of the rigid solid, which is flexible, malleable, and lustrous. They are an excellent conductor of electricity and thermal conductivity.

Complete step by step answer:
We know that the purpose of the formation of alloy is generally to increase the hardness of metal and to improve the malleability of metals. The general meaning of malleability is to make it versatile or flexible to gain any shape. It also increases the resistance power of metal or makes it corrosion-free.
Generally, pure metal is softer than its alloy because it enhances the property of hardening.
The pure metals have a high melting point, but the melting point of the alloy is usually lower than its original metal.
One of the essential desires of attaining the good castings for the expansion of the metal by the process named as solidification. The pure molten metals go through the contraction of metals on the solidification process. So, the metals are alloyed for approaching the good casting process.

Hence, the correct option for this question is D; that is all of the above which consist the point to improve the malleability of metals, to increase the hardness of metal and to increase its resistance to corrosion.

Alloy formation generally enhances the corrosion resistance property of the metal. It also increases the hardness of that metal. The melting point of metal is higher than from its alloy.
